  1. 1. De Sitter & String Theory
    Pablo Soler
    24/11/2020, 13:00
    In this talk I will briefly describe some aspects related to de Sitter constructions in string theory, both related to specific string scenarios (in particular the KKLT scenario) as well as conjectural constraints arising within the Swampland program.

  2. 2. Yukawa Couplings computations for T-branes
    Mohsen Karkheiran
    24/11/2020, 13:20
    In a 4D F-theory model, Yukawa couplings can be appear in various ways. Generically, triple intersection of 7-branes appear as Yukawa couplings in the 4D effective theory. But this is not the only way. Once there are non-vanishing fields living inside the 7-brane, we may also get Yukawa couplings in the effective theory coming from these bulk fields and/or from the fields living over curves...

  3. 3. Orbifold and SCFT pairs
    Peter Merkx
    24/11/2020, 13:40
    Cyclic quotient surface singularity isomorphism classes have long been known to come with a natural duality structure, but a distinct orbifold duality not seemingly present in the mathematics literature appears to arise naturally via the interplay between 6D SCFTs and an infinite subset of these same types of orbifolds. We will discuss each of these dualities and the related structures they...

  4. 0. Landscape of BSM physics scenarios at neutrino oscillation experiments.
    Mehedi Masud
    24/11/2020, 14:30
    After the discovery of neutrino oscillation, the focus of the community is now on various fundamental pressing issues such as, the search for leptonic CP-Violation, determination of the ordering of neutrino masses and the precision measurement of the oscillation parameters. Several powerful, high-precision neutrino experiments are in the pipeline to address these issues and these...

  5. 4. Big Bounce Baryogenesis
    Neil Barrie
    24/11/2020, 14:50
    We explore the possibility of an Ekpyrotic contraction phase harbouring a mechanism for Baryogenesis. A Chern-Simons coupling between the fast-rolling Ekpyrotic scalar and the Standard Model Hypercharge gauge field enables the generation of a non-zero helicity during the contraction phase. The baryon number subsequently produced at the Electroweak Phase Transition is consistent with...

  6. 5. Model building in Pati-Salam models
    Junichiro Kawamura
    24/11/2020, 15:10
    In this talk, I will briefly introduce my recently working projects related to Pati-Salam unification. The Pati-Salam unification is an attractive candidate for a UV completion of the Standard Model (SM), because the SM quarks and leptons are unified into only two multiplets under the Pati-Salam symmetry, electric charges are quantized and too fast proton decay is not induced by extra...
