          Past HEPD Seminars in:   2016;    2015;    2014;    2013;    2012;    2011;    2010;    2009;    2008;    2007;    2006;    2005;    2004;    2003;   

  • Next seminar:  
    Topic:  "Electron-Ion Collider ."    
    (Abstract - The project of an Electron-Ion Collider (EIC) in USA is currently discussed as a next-generation facility to study high-energy nuclear physics beyond 2025, when Relativistic Heavy Ion Collider (RHIC, BNL) and Jefferson Lab will have reached their goals. The EIC machine designs are aimed at achieving variable center of mass energies of 20-100 GeV, upgradable to 150 GeV, high degree of polarization (~70%) of beams of electrons, protons and light nuclei, high collision luminosity of 10^{33-34} cm-2s-1, and ion beams from deuteron to heaviest (Lead) nuclei. The main goal of the EIC is to study fundamental questions of Quantum Chromodynamics, which include origin of the nucleon spin and the three-dimensional structure of the nucleon in terms of quarks and gluons, the new state of ultra-dense gluon matter (saturation), and influence of nuclear matter on distributions of quarks and gluons and propagation of color charges through it. The talk will present the current status of the EIC project, its physics program, and proposed designs of EIC realization.)

  • Joint Seminar    H  E  P  D   -   T P  D  :  
    Topic:  "The boiling QCD vacuum : BEC study with ATLAS LHC experiment from 900 GeV till 13 TeV."     .
    (Abstract - Bose-Einstein correlations (BEC) of identical secondaries is a way to study the space-time structure of high energy interaction. The interaction is mediated by the Pomeron exchange - an object with a vacuum quantum numbers which can be considered as an vacuum exitation. BEC in proton-proton collisions at the LHC are well described by the formula with two different scales where the small scale corresponds to the Pomeron (vacuum exitation) size. It is shown for the first time that the pions are produced by few small size sources distributed over a much larger area in impact parameter space occupied by the interaction amplitude.)

    A classical point electron with finite mass.
      (manay-hepd-28-03-17.pdf)
    (Abstract - It is argued that the gravitational force can play a crucial role in the structure of leptons.
    The exact Reissner-Nordstr$\ddot{o}$m solution of the Maxwell and Einstein equations corresponding the gravitational field configuration localized in the region with the range of about $10^{-34}$ cm is discussed. It is shown that the electromagnetic mass of the classical electron is finite and by about $10^{21}$ times larger than the experimental electron mass. The contribution of the gravitational interaction to the total electron mass is negative and makes the mass equal to its experimental value.)

    Magnetic storage of ultracold neutrons and neutron lifetime measurement.  
    (Abstract   -   Precision measurements of the neutron lifetime provide stringent tests of the standard electroweak model as well as crucial inputs for tests of Big-Bang nucleosynthesis. The present world average of the neutron lifetime is dominated by results obtained using material bottles for UCNs. Since the two most precise results for the neutron lifetime were obtained using trapped UCN in material bottles, the large discrepancy between the values indicate that systematic effects are not fully under control. New alternative measuring techniques are then called for. A prototype of a magneto-gravitational trap has been successfully tested at ILL and a value of the neutron lifetime has been obtained with a statistical precision of 1.9 s. The main features and advantages of experimental setup are discussed. A trap of larger volume is presently being designed to improve the statistical precision. )   (Ezhov-31.01.2017.pdf)
