Spontaneous parity breaking and supersymmetry breaking in metastable vacua with consistent
We study the compatibility of spontaneous breaking of parity and successful cosmology in a left-right symmetric model where supersymmetry breaking is achieved in metastable vacua. We show that domain walls for...

Open AccessTunneling decay of false vortices with gravitation
We study the effect of vortices on the tunneling decay of a symmetry-breaking false vacuum in three spacetime dimensions with gravity. The scenario considered is one in which the initial state, rather than bei...

Open AccessNeutrino mass, mixing and muon g − 2 explanation in \( \mathrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} \) extension of left-right theory
We consider a gauged U 1 ...

Open AccessVacuum structure of Alternative Left-Right Model
We investigate an Alternative Left-Right Model (ALRM) with SU(2)L as well as SU(2)R gauge groups, but unlike the traditional left-right symmetric models (LRSM) is not symmetric under the exchange of the fermion c...

Open AccessDark matter in the Alternative Left Right model
The Alternative Left-Right Model is an attractive variation of the usual Left-Right Symmetric Model because it avoids flavour-changing neutral currents, thus allowing the additional Higgs bosons in the model t...

Open AccessCharge imbalance resolved Rényi negativity for free compact boson: Two disjoint interval case
In this paper, we study the symmetry decomposition of Rényi negativity into charge imbalance sectors for the 1+1 dimensional free compact boson field with a global U(1) symmetry in the ground state for the cas...

Open AccessGravitational wave signature of generic disappearance of Z2-symmetry breaking domain walls
Breaking of discrete parity at high scale gives rise to Z2-domain walls (DW). The metastability of such walls can make them relatively long lived and contradict standard cosmology. We consider two classes of theo...

Open AccessMulti-charged moments and symmetry-resolved Rényi entropy of free compact boson for multiple disjoint intervals
We study multi-charged moments and symmetry-resolved Rényi entropy of free compact boson for multiple disjoint intervals. The Rényi entropy evaluation involves computing the partition function of the theory on...
