      On January 6th , Erik Verlinde (a string theorist well known for his Matrix theory work) submitted a paper (arXiv) to arXiv entitled "On the Origin of Gravity and the Laws of Newton", in which he derives Newton's law of gravitation by assuming the microscopic structure of space-time is holographic. This led to a flurry of follow up papers, including notable notes by Lee Smolin.   In particular, if the intermediate transverse momentum is between 1 and 3 GeV, the near-side ("delta phi" near zero or pi) associated yield begins to dramatically grow with the multiplicity and the rapidity difference, producing a long-range ridge-like structure. Possible Signals of new phenomena in hadronic interactions at dn/deta=+

    In order to facilitate the deployment of modern data science technologies (e.g., Deep Learning) into theoretical and experimental research in high energy physics, we suggest that the creation of a European Data Science Institute for Fundamental Physics is included among the recommendations of the European Strategy group. Such an institute would facilitate the development of. DeVorkin: I am with Professor Masatoshi Koshiba, Professor Emeritus — is that correct? — of physics, the University of Tokyo. And the auspices of the interview are the American Institute of Physics. Please state your name. Koshiba: My name is Koshiba, Masatoshi Koshiba. Just call me Toshi. DeVorkin: Toshi. Okay. Toshi, could you tell me something about your family, who your.

      four states are one prior to the big bang and the four forces depend on the four states so they are also one. E=MC^2 depends on momentum an momentum is determined by state. This is a means for a Big crunch to store the potential energy of a prexisting universe and release it as Kinetic energy in the big bang.   This means that in one year (~3 x 10 7 sec) in a MeV energy bin around 1 GeV you would get about 3 x 10 7 particles per m 2-sr. If you assume a scale height for the atmosphere (say 50 km), it has an acceptance of (4*pi*(x10 3)) 2 or x 10 9 m 2 -sr which would give you (3 x 10 7) x (6 x 10 9) = x 10 17 particles per year.

Four and five-body final state interactions in [pi]-p collisions at 7 GeV/C by Thomas Francis Johnston Download PDF EPUB FB2

The study is carried out in the impulse approximation (IA) i.e. the final state interactions are neglected. The elementary amplitude for pion electroproduction is taken from the MAID model. Using fb-1 of e+e- collision data collected at center-of-mass energies around GeV, we search for time-integrated CP violation in the Cabibbo-suppressed decays D0/D̅ 0→π-π+π0 and D0.

The mass matrix of the sfermions can be written as [, ] right-handed (ũ c,d c,ẽ c) sfermions in equation (); m f is the Yukawa-type mass of the corresponding fermions; A f is the.

So the Omega_b must travel away from the interaction point, where it has been produced. A cut on the travel path of the J/Psi - Omega system does the trick, and improves dramatically the signal to background fraction. It is this latter selection that accepts only 35 events in the GeV.

Results are presented from a search for the rare decays B(s) to mu+ mu- and B0 to mu+ mu- in pp collisions at sqrt(s) = 7 and 8 TeV, with data samples corresponding to integrated luminosities of 5. We present a search for heavy Majorana neutrinos, using pp collision data collected with the CMS detector at the centre-of-mass energy of 13 TeV in The search targets for heavy neutrino in the Type-I seesaw mechanism where the mass ranges from 20 GeV to GeV, which is wider range than the study performed using the 8 TeV data.

Fifthly the fundamental particulate state of the Vikrithi or Neutrino as Ne = My (L2) (2 pi/7)2. Sixthly, the fundamental fraction of a time-cycle of simultaneity when the difference between the static and dynamic state is nil as Tcy = My (L)/7 and equals the Planck time in quantum theory.

J Button-Shafer's research works with 8, citations andreads, including: The Physics of the B Factories. Fermi's four-fermion interaction (responsible for beta decay i.e.

weak interactions) and pure general relativity (responsible for gravity) are canonical examples. Such theories need genuine modifications of the short-distance laws of physics to get rid of the infinities. In March, ATLAS has moderately excited us with a 3-sigma SUSY-like excess in final states with a lepton pair, jets, and MET.

At the end of another blog post, I mentioned a paper explaining it in terms of a light sbottom. There's a different explanation on the arXiv now, extending the proposal by Ullwanger 3 weeks ago. It's been a lot of time after the Big Bang so Shang, Yang, Yang Zhang, and.

Summing the muons momenta, we can see that the pair mass (93 GeV/c 2) is quite close to a Z boson mass (91 GeV/c 2). In the next post, we will see the three levels of the ATLAS trigger system with increasing complexity and accessing each time more details of the detector.

The fine structure constant α, is the coupling constant characterizing the strength of the electromagnetic interaction (the parameter that describes coupling between light and relativistic electrons and is traditionally associated with quantum electrodynamics) that keeps the atom and the whole universe together.

The name comes from the fact. However, they can be created in high-energy collisions at particle accelerators or in interactions between cosmic rays and atoms in the atmosphere. Ds(). The BaBar team used data from electron-positron collisions at the PEP-II asymmetric storage ring at SLAC.

In the last decades, a very important breakthrough has been brought about in the elementary particle physics by the discovery of the phenomenon of the neutrino oscillations, which has shown neutrino properties beyond the Standard Model.

But a full understanding of the various aspects of the neutrino oscillations is far to be achieved. In this paper the theoretical background of the neutrino. SUS Search for stop pairs in the 0L final state at 13 TeV (Combined) EXO Search for pair production of second generation leptoquarks EXO Updated search for high mass-resonances in diphoton final state including 0T dat EXO Search for leptophobic Z' decaying into four leptons in the final state at sqrt(s) = 8 TeV.

In summary, the current unexplored regions of the SM Higgs mass are GeV/c 2 and GeV/c 2. Or more precisely, if the SM Higgs boson does exist, then it will most likely have a mass between GeV/c 2 or GeV/c^2, and for some portions of these ranges the Higgs will decay over 90% of the time to a W + W – Pair!!.

From the interaction of about 10 7 antiprotons and 7 × 10 8 positrons, we observed 38 annihilation events consistent with the controlled release of trapped antihydrogen from our magnetic trap; the measured background is ± events. This result opens the door to precision measurements on anti-atoms, which can soon be subjected to the.

This is in agreement with the latest direct searches at the LHC, which constrain the Higgs mass to less than GeV/c 2, and direct-search limits from the Tevatron, which point to a Higgs mass of less than GeV/c 2, before the update of their results expected this week.

May June 5 UConn Physics Department hosted an international summer school Strong interactions beyond simple factorization: collectivity at high energy from initial to final state. The school was supported by an NSF grant to Prof.

Kovner and was devoted to modern approaches to the physics of high energy hadronic and heavy ion collisions. While the certainty isn't enough for a formal discovery, it's being claimed that the signal is equivalent to 3+ standard deviations or so, about % confidence level.

The expected background was \(\) events. But what I find remarkable is the precision with which they dare to suggest the mass of the WIMP: it seems to be \(\GeV\). Now to change gears quite a bit, I’d like to share another link that has been making a splash in particle physics circles: a typed up version of Sidney Coleman’s Physics a quantum field theory course at Harvard, thanks to the heroic typesetting efforts of Bryan Gin-ge Chen and Ting Yuan Sen.
