  1. 428. (G*) Characterization and Calibration of the ALPHA-g Barrel Veto Detector

    Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

    Since trapping the first cold antihydrogen atoms over 10 years ago, the ALPHA collaboration has established itself at the leading edge of antimatter science. Through a series of experiments located at the Antiproton Decelerator at CERN, the group has carried out a number of novel precision measurements, primarily on the spectral transitions of antihydrogen. ALPHA-g is the latest addition to...

  2. 335. Is New Physics Needed to Explain the ATOMKI Anomaly?
    Prof. Aleksandrs Aleksejevs (Memorial University of Newfoundland)

    Nuclear Physics / Physique nucléaire (DNP-DPN)
    Oral (Non-Student) / Orale (non-étudiant(e))

    Do we really need a hypothetical gauge boson, "X17", to explain the famous ATOMKI measurements? Or can there be some interplay between the theoretical and experimental effects? We show that the bump in the $^8Be(18.15)\rightarrow ^8Be +e^++e^-$ decay data can be reproduced within the Standard Model by adding the full set of second-order corrections and the interference terms to the Born-level...

  3. 212. (U*) Ab initio calculations of electric dipole moments of light nuclei

    Oral Competition (Undergraduate Student) / Compétition orale (Étudiant(e) du 1er cycle)

    In any finite system, the presence of a non-zero permanent electric dipole moment (EDM) would require both parity (P) and time-reversal (T) violation. The standard model predicts a very small CP violation and consequently any observation of the EDM would imply physics beyond the standard model. Thus, EDMs have long been proposed as a way to test these fundamental symmetries. Experimental...

  4. 318. Ab initio calculations of heavy nuclei
    Takayuki Miyagi (TRIUMF)

    Nuclear Physics / Physique nucléaire (DNP-DPN)
    Oral (Non-Student) / Orale (non-étudiant(e))

    An ab initio nuclear many-body calculation needs the nucleon-nucleon (NN) and three-nucleon (3N) matrix elements as an input. The NN matrix elements can be prepared in a sufficiently large space, while the 3N matrix elements are significantly limited. Due to the limitation, it is challenging to obtain reliable results for the system heavier than $A \sim 100$. Since we usually do not use all...
