Abstract: A bstractWe show that F-theory compactifications with abelian gauge factors generally exhibit a non-trivial global gauge group structure. The geometric origin of this structure lies with the Shioda map of the Mordell-Weil generators. This results… read more here.

Abstract: We analyse global anomalies and related constraints in the Standard Model (SM) and various Beyond the Standard Model (BSM) theories. We begin by considering four distinct, but equally valid, versions of the SM, in which… read more here.

Abstract: A bstractCoulomb branches of a set of 3dN$$ \mathcal{N} $$ = 4 supersymmetric gauge theories are closures of nilpotent orbits of the algebra son$$ \mathfrak{so}(n) $$. From the point of view of string theory, these… read more here.

DOI: 10.1088/1361-6382/aa9fd5
Abstract: The variety of consistent ‘gauging’ deformations of supergravity theories in four dimensions depends on the choice of Lagrangian formulation. One important goal is to get the most general deformations without making hidden assumptions. Ignoring supersymmetry… read more here.

DOI: 10.1103/physrevd.105.015032
Abstract: In this paper, we present a model which attempts to unify a new dark sector force with a local SU(3) flavor symmetry. Dark Matter (DM) and its potential interactions with the Standard Model (SM) continue… read more here.

DOI: 10.1103/physrevd.98.011701
Abstract: The models with the gauge group $SU(3)_c\times SU(3)_L \times U(1)_X$ (331-models) have been advocated to explain why there are three fermion generations in Nature. As such they can provide partial understanding of the flavour sector.… read more here.
