Acceleration of Electron in Plasma Waves

Authors: George Rajna
Comments: 82 Pages.

As an alternative cost-cutting option to accelerate particles more efficiently, the wakefield accelerator has been suggested. Physicists send a beam of either electrons, protons, or a laser through a plasma. [44] A KAIST research team successfully identified the underlying principles behind electron heating, which is one of the most important phenomena in plasmas. [43] Researchers at MIT's Plasma Science and Fusion Center (PSFC) have now demonstrated how microwaves can be used to overcome barriers to steady-state tokamak operation. [42] Plasma particle accelerators more powerful than existing machines could help probe some of the outstanding mysteries of our universe, as well as make leaps forward in cancer treatment and security scanning—all in a package that's around a thousandth of the size of current accelerators. [41] The Department of Energy's SLAC National Accelerator Laboratory has started to assemble a new facility for revolutionary accelerator technologies that could make future accelerators 100 to 1,000 times smaller and boost their capabilities. [40] The authors designed a mechanism based on the deployment of a transport barrier to confine the particles and prevent them from moving from one region of the accelerator to another. "There is strong experimental evidence that there is indeed some new physics lurking in the lepton sector," Dev said. [38] Now, in a new result unveiled today at the Neutrino 2018 conference in Heidelberg, Germany, the collaboration has announced its first results using antineutrinos, and has seen strong evidence of muon antineutrinos oscillating into electron antineutrinos over long distances, a phenomenon that has never been unambiguously observed.

Finding Gluon Inside the Pion

Authors: George Rajna
Comments: 84 Pages.

Researchers from NC State University have determined the probability of finding a gluon inside the pion. [44] An international joint research group led by Osaka University demonstrated that it was possible to efficiently heat plasma by focusing a relativistic electron beam (REB) accelerated by a high-intensity, short-pulse laser with the application of a magnetic field of 600 tesla (T), about 600 times greater than the magnetic energy of a neodymium magnet (the strongest permanent magnet). [43] Researchers at MIT's Plasma Science and Fusion Center (PSFC) have now demonstrated how microwaves can be used to overcome barriers to steady-state tokamak operation.

Fusion Power Plants

Authors: George Rajna
Comments: 83 Pages.

A class exercise at MIT, aided by industry researchers, has led to an innovative solution to one of the longstanding challenges facing the development of practical fusion power plants: how to get rid of excess heat that would cause structural damage to the plant.

Excess of Electron Neutrinos

Authors: George Rajna
Comments: 49 Pages.

A pair of researchers with the Niels Bohr Institute in Denmark has come up with a possible explanation for the excess of electron neutrinos detected by researchers at the IceCube Neutrino Observatory. [18] The largest liquid-argon neutrino detector in the world has just recorded its first particle tracks, signaling the start of a new chapter in the story of the international Deep Underground Neutrino Experiment (DUNE). [17] While these experiments seem miniature in comparison to others, they could reveal answers about neutrinos that have been hiding from physicists for decades. [16] In a paper published today in the European Physical Journal C, the ATLAS Collaboration reports the first high-precision measurement at the Large Hadron Collider (LHC) of the mass of the W boson. [15] A team of researchers at the University of Michigan has conducted a thought experiment regarding the nature of a universe that could support life without the weak force. [14] The international T2K Collaboration announces a first indication that the dominance of matter over antimatter may originate from the fact that neutrinos and antineutrinos behave differently during those oscillations. [13] Neutrinos are a challenge to study because their interactions with matter are so rare. Particularly elusive has been what's known as coherent elastic neutrino-nucleus scattering, which occurs when a neutrino bumps off the nucleus of an atom. [12]

Supersymmetry Breaking

Authors: George Rajna
Comments: 32 Pages.

Supersymmetry predicts that two basic classes of fundamental particles, fermions and bosons, accompany each other in the same representation. [29] A fraction of a second after the Big Bang, a single unified force may have shattered. Scientists from the CDF and DZero Collaborations used data from the Fermilab Tevatron Collider to recreate the early universe conditions. [28] Now researchers at the Paul Scherrer Institute PSI have helped to better understand the first minutes of the universe: They collected artificially produced beryllium-7 and made it into a sample that could be investigated. [27] Researchers have developed a new way to improve our knowledge of the Big Bang by measuring radiation from its afterglow, called the cosmic microwave background radiation. [26] The group's results reinforce a disagreement over the value of the Hubble constant as measured directly and as calculated via observations of primordial radiation – a disparity, say the researchers, which likely points to new physics. [25] Neutron stars consist of the densest form of matter known: a neutron star the size of Los Angeles can weigh twice as much as our sun. [24] Supermassive black holes, which lurk at the heart of most galaxies, are often described as "beasts" or "monsters". [23] The nuclei of most galaxies host supermassive black holes containing millions to billions of solar-masses of material. [22] New research shows the first evidence of strong winds around black holes throughout bright outburst events when a black hole rapidly consumes mass. [21] Chris Packham, associate professor of physics and astronomy at The University of Texas at San Antonio (UTSA), has collaborated on a new study that expands the scientific community's understanding of black holes in our galaxy and the magnetic fields that surround them. [20] In a paper published today in the journal Science, University of Florida scientists have discovered these tears in the fabric of the universe have significantly weaker magnetic fields than previously thought.

Lifetime Hierarchy of Subatomic Particles

Authors: George Rajna
Comments: 36 Pages.

Researchers in the College of Arts and Sciences have determined that the lifetime of the so-called charmed omega—part of a family of subatomic particles called baryons—is nearly four times longer than previously thought. [27] Prof. Witek led a five-member group of physicists from Cracow searching for nonresonant decays of charmed baryon Lambda c in data collected in 2011 and 2012 by the international LHCb experiment at the Large Hadron Collider in Geneva. [26] The announcement was made during the CHARM 2018 international workshop in Novosibirsk in Russia: a charming moment for this doubly charmed particle. [25] The group, in work published in Physical Review Letters, has now used powerful theoretical and computational tools to predict the existence of a "most strange" dibaryon, made up of two "Omega baryons" that contain three strange quarks each. [24] The nuclear physicists found that the proton's building blocks, the quarks, are subjected to a pressure of 100 decillion Pascal (10 35) near the center of a proton, which is about 10 times greater than the pressure in the heart of a neutron star. [23] In experimental campaigns using the OMEGA EP laser at (MIT) researchers took radiographs of the shock front, similar to the X-ray radiology in hospitals with protons instead of X-rays. [22] Researchers generate proton beams using a combination of nanoparticles and laser light. [21] Devices based on light, rather than electrons, could revolutionize the speed and security of our future computers. However, one of the major challenges in today's physics is the design of photonic devices, able to transport and switch light through circuits in a stable way. [20] Researchers characterize the rotational jiggling of an optically levitated nanoparticle, showing how this motion could be cooled to its quantum ground state. [19] Researchers have created quantum states of light whose noise level has been " squeezed " to a record low. [18] An elliptical light beam in a nonlinear optical medium pumped by " twisted light " can rotate like an electron around a magnetic field. [17]

Antarctica Don't Fit Standard Model

Authors: George Rajna
Comments: 50 Pages.

A team of researchers at Penn State University has found new evidence that suggests some particles detected in Antarctica do not fit the Standard Model. [30] In a recent study, the CMS collaboration describes how it has sifted through data from the Large Hadron Collider (LHC) to try and spot dark quarks. [29] Physicists in Italy are about to start up a new experiment designed to hunt for hypothetical particles such as the " dark photon " and carriers of a possible fifth force of nature. [28] A signal caused by the very first stars to form in the universe has been picked up by a tiny but highly specialised radio telescope in the remote Western Australian desert. [27] This week, scientists from around the world who gathered at the University of California, Los Angeles, at the Dark Matter 2018 Symposium learned of new results in the search for evidence of the elusive material in Weakly Interacting Massive Particles (WIMPs) by the DarkSide-50 detector. [26] If they exist, axions, among the candidates for dark matter particles, could interact with the matter comprising the universe, but at a much weaker extent than previously theorized. New, rigorous constraints on the properties of axions have been proposed by an international team of scientists. [25] The intensive, worldwide search for dark matter, the missing mass in the universe, has so far failed to find an abundance of dark, massive stars or scads of strange new weakly interacting particles, but a new candidate is slowly gaining followers and observational support. [24] " We invoke a different theory, the self-interacting dark matter model or SIDM, to show that dark matter self-interactions thermalize the inner halo, which ties ordinary dark matter and dark matter distributions together so that they behave like a collective unit. " [23] Technology proposed 30 years ago to search for dark matter is finally seeing the light. [22]
