  1. 922. Charged gravitational instantons: extra CP violation and charge quantisation in the Standard Model
    Archil Kobakhidze (The University of Sydney)

    10. Formal Theory
    Poster

    We argue that quantum electrodynamics combined with quantum gravity results in a new source of CP violation, anomalous non-conservation of chiral charge and quantisation of electric charge. Further phenomenological and cosmological implications of this observation are briefly discussed within the standard model of particle physics and cosmology

  2. 199. Electroweak magnetic monopole: The lower mass bound
    Dr Petr Beneš (Czech Technical University in Prague)

    10. Formal Theory
    Poster

    We present exact solutions to the electroweak Cho-Maison magnetic monopole in a family of effective extensions of Standard Model that have a Bogomol’nyi-Prasad-Sommerfield (BPS) limit. We find that the lower bound to the mass of the magnetic monopole is $M \geq 2\pi v/ g \approx 2.37\,\,\mathrm{TeV}$. We argue that this bound holds universally, not just in theories with a BPS limit.

    10. Formal Theory
    Poster

    SO(5)\times U(1) \times SU(3) gauge-Higgs unification model inspired by
    SO(11) gauge-Higgs grand unification is constructed in the Randall-Sundrum
    warped space.
    The 4D Higgs boson is identified with the Aharonov-Bohm phase in the
    fifth dimension.
    Fermion multiplets are introduced in the bulk in the spinor, vector and singlet
    representations of SO(5) such that they are implemented in the...

  4. 826. A gauge invariant description of phase transitions
    Dr Andreas Ekstedt (Institute of Particle and Nuclear Physics, Charles University)

    10. Formal Theory
    Poster

    Phase transitions are of wide interest to be sure; whether it's in superconductors or the early universe: Beyond the Standard Model scenarios like Baryogenesis cry out for a strong first-order phase transition. So a precise description of phase transitions is vital.
    Phase transitions are, in field theory, studied with numerical methods (lattice) and perturbative calculations (the effective...
