  1. 122. The quantum nature of the "minimal" SO(10) GUT

    Talk

    In this talk I will present the latest developments on the minimal potentially realistic non-supersymmetric SO(10) GUT model with the scalar sector consisting of 45+126+10. This model is known to suffer from tachyonic instabilities in the spectrum at tree-level, but quantum corrections to the scalar potential may cure this problem - a route worth investigating, since this particular SO(10) GUT...

  2. 93. New results on the neutron to hidden neutron oscillations hypothesis

    Neutron to hidden neutron oscillation (n − n') experiments
    are one of the several probes for testing the existence of hidden sector worlds [1,
    2]. Although hidden states of matter were originally proposed to restore, on a
    general picture, the breaking of P and CP symmetries [4], currently they also
    correspond to candidates for dark matter [3]. In this work, we present a new
    experimental...

  3. 85. Testing the Pauli Exclusion Principle and Collapse models in underground experiments

    Talk

    The Pauli Exclusion Principle (PEP) is one of the main
    cornerstones of the Quantum Theory. Violation of the PEP, albeit small, could be
    motivated by physics beyond the Standard Model which entail extra space
    dimensions, violation of the Lorentz invariance, non-commutative space-time.
    These scenarios can be experimentally constrained with stat-of-the-art X-ray
    spectroscopy, searching for...

  4. 131. Implications of a matter-antimatter mass asymmetry in Penning-trap experiments

    Talk

    Lorentz-invariance, and locality indicate a conservation of CPT in a causal, unitary and Hermitian quantum field theory, implying that fundamental properties of particles and antiparticles should be equal in magnitude. We compare experiments that could test the mass difference between a particle and its antiparticle and pay a special attention to the Penning trap experiments, which test CPT...

  5. 23. Anatomy of scalar mediated proton decays in SO(10) models
    Saurabh Kumar Shukla (Physical Research Laboratory)
    All
    Talk

    Any grand unified model is plagued with particles capable of inducing
    proton decay. Identifying all potential scalar proton decay mediators
    stemming from different irreducible representations of SO(10), we
    will show their coupling with the Standard Model fermions, tree-level
    contributions of the effective strength of $B-L$ conserving($d=6$),
    and $B-L$ violating($d=7$) operators to proton...
