  1. 86. Studies of discrete symmetries in positronium decays using the J-PET tomograph
    Paweł Moskal
    6/7/22, 9:00 AM

    The Jagiellonian Positron Emission Tomograph (J-PET) is the first PET scanner based on plastic scintillators.

    It is designed to measure momentum vectors and the polarisation of photons originating from the decays of positronium.

    In combination with the newly invented positronium imaging method, J-PET enables the study of discrete symmetries
    in positronium without the use of magnetic...

  2. 40. Particle Physics with Neutrino Detector in Space
    Nickolas Solomey (Wichita State University)
    6/7/22, 9:30 AM

    The question of what type of new physics could be done if a neutrino detector was able to operate close to the Sun was initially raised in 2015. This idea at the time was completely unexplored but innovative. Since asking this question we have determined how such a detector might be operated in space with little shielding and have explored scientific outcomes: better understanding of the solar...

  3. 45. ATLAS measurements of CP violation and rare decay processes with beauty mesons
    Adam Barton
    6/7/22, 9:55 AM

    The ATLAS experiment has performed measurements of $B$-meson rare decays proceeding via suppressed electroweak flavour changing neutral currents, and of mixing and CP violation in the neutral $B^{0}_{s}$ meson system. This talk will focus on the latest results from the ATLAS collaboration, such as rare processes $B^{0}_{s}\rightarrow\mu\mu$ and $B^{0}_{d}\rightarrow\mu\mu$ and CP violation in...

  4. 91. J-PET tomograph as a novel detector for discrete symmetries studies in charge leptonic system
    SUSHIL SHARMA (Jagiellonian University)
    6/7/22, 10:50 AM

    The J- PET tomograph, which consists of inexpensive plastic scintillators, has also demonstrated its
    potential in the study of fundamental symmetries [1,2]. It consists of 192 plastic scintillators arranged
    in 3 layers optimized for the registration of multiple annihilation photons emitted in the decays of
    ortho-positronium atoms (o-Ps) [3], a triplet state of a purely charged leptonic...

  5. 64. Measurement of the rare K+ to pi+ nu nubar decay
    Gemma Tinti
    6/7/22, 11:15 AM

    The decay K+→π+ νν ̅, with a very precisely predicted branching ratio of less than 10-10, is among
    the best processes to reveal indirect effects of new physics.
    The NA62 experiment reports the branching ratio measurement BR(K+→π+νν¯) =
    (10.6+4.0−3.4|stat ± 0.9syst) × 10−11 at 68% CL, based on the observation of 20 signal candidates
    with an expected background of 7.0 events from the total...

  6. 88. Production of enigmatic X(3872) in proton-proton collisions and its structure
    Prof. Szczurek Antoni (INP PAS)
    6/7/22, 11:40 AM
  7. 66. The physics case for the CP-violation tests in hyperon decays at SCTF
    Nora Salone (National Centre for Nuclear Research)
    6/7/22, 1:10 PM

    A comparison of the hyperon and antihyperon decay parameters allows for tests of direct CP-symmetry violation complementary to the \epsilon'/\epsilon measurements in kaon decays. Importance of the new BESIII result on e+e- ->J/psi->Xi- bar-Xi+, where the final state interaction and weak phase difference are disentangled, is discussed. We show how future measurements at Super Charm-Tau...

  8. 63. Precision measurements with Kaons at CERN
    Chris Parkinson
    6/7/22, 1:35 PM

    The NA62 experiment at CERN took data in 2016--2018 with the main goal of measuring the K+ -> pi+ nu nubar decay. The high-intensity fixed-target setup and the detector performance make the NA62 experiment particularly suited to investigate the Standard Model structure and its possible extensions with
    precision measurements of charged kaon decays.
    Results from studies of the radiative kaon...

  9. 47. ATLAS results on $B_{c}$ production and decays

    Recent results on $B_{c}$ production and decays from the proton-proton collision data taken by the ATLAS experiment will be presented. The measurement of the differential ratios of $B_{c}^{+}$ and $B^{+}$ production cross sections at 8 TeV will be shown. New results on $B_{c}$ decays to $J/\psi D_{s}^{(*)}$ final states obtained with the Run 2 data at 13 TeV will also be reported.

  10. 46. ATLAS results on charmonium production

    Recent results from the proton-proton collision data taken by the ATLAS experiment on charmonium production will be presented. The measurement of $J/\psi$ and $\psi(2S)$ differential cross sections will be reported as measured on the whole Run 2 dataset. Results on associated production of prompt $J/\psi$ and $W$ bosons in the 8 TeV data will be shown.
