  1. 3919. (I) The Neutron Beta Decay Experiment (Nab) and Canada’s Role using the Manitoba II 30 keV Proton Source
    Nick Macsai (University of Manitoba)

    Symposia Day (DNP - DPN) - Precision Physics and Tests of Fundamental Symmetries | Physique de précision et tests des symétries fondamentales
    Invited Speaker / Conférencier(ère) invité(e)

    Neutron beta decay is a fundamental nuclear process that provides a means
    to perform precision measurements that test the limits of our present under-
    standing of the weak interaction described by the Standard Model of particle
    physics and puts constraints on physics beyond the Standard Model. The Nab
    experiment will measure ‘a’, the electron-neutrino angular correlation parameter,
    to a...

  2. 3975. (I) Radioactive molecules for fundamental physics at TRIUMF
    Dr Ivana Belosevic (TRIUMF)

    Symposia Day (DNP - DPN) - Precision Physics and Tests of Fundamental Symmetries | Physique de précision et tests des symétries fondamentales
    Invited Speaker / Conférencier(ère) invité(e)

    In the past few years, the prospect of probing fundamental symmetries with radioactive molecules has generated significant interest in the field of low-energy, high-precision tests of the Standard Model of particle physics. Indeed, tailored molecules containing short-lived radioactive atoms are predicted to be especially sensitive to violations of fundamental symmetries such as a permanent...

  3. 3881. (G*) Observation of magnetic dipole M1 transition in francium: A key step towards measuring atomic parity violation
    Ms Anima Sharma (university of manitoba)

    Symposia Day (DNP - DPN) - Precision Physics and Tests of Fundamental Symmetries | Physique de précision et tests des symétries fondamentales
    Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

    Low-energy precision electro-weak physics tests are advocated as part of the search for physics beyond the Standard Model. We are working towards a measurement of atomic parity violation (APV) in francium (Z = 87), the heaviest alkali, in a magneto-optical trap (MOT) online to ISAC at TRIUMF. The transition of interest in Fr is between the 7S and 8S states, where the parity violating (PV)...

  4. 3789. (G*) Laser Calibration Studies Using the ALPHA-g Detector
    Pooja Woosaree (Dep. of Phys. and Astronomy University of Calgary (CA))

    Symposia Day (DNP - DPN) - Precision Physics and Tests of Fundamental Symmetries | Physique de précision et tests des symétries fondamentales
    Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

    ALPHA-g has completed a successful run in 2022 in the pursuit of measuring the gravitational mass of antihydrogen. This apparatus was designed to test whether antimatter follows Einstein’s Weak Equivalence Principle (WEP), where the acceleration due to gravity that a body experiences is independent of its structure or composition. A measurement of the gravitational mass of antimatter has never...

  5. 3839. (G*) Storage lifetime of ultracold neutrons in superfluid helium between 1.0 K and 1.8 K

    Nuclear Physics / Physique nucléaire (DNP-DPN)
    Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

    Ultracold neutrons (UCNs) are a powerful tool for probing fundamental physics, enabling precision measurements in a variety of research areas, such as beta decay, electric dipole moments, and gravitational quantum states. To advance these experimental efforts it is necessary to develop new, high-density UCN sources capable of providing order-of-magnitude improvements in statistical...

  6. 3898. (G*) STUDIES OF 198Hg(d, d’) INELASTIC SCATTERING REACTION

    Nuclear Physics / Physique nucléaire (DNP-DPN)
    Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

    Motivated by fundamental symmetry tests, a non-zero measurement of a permanent electric dipole moment (EDM) would represent a clear signal of the violation of the CP symmetries. The imbalance in the matter and antimatter observed in our Universe is believed to arise from such violations, although the amount that is present in the Standard Model (SM) is insufficient. Many extensions to the SM...
