Modular Scotogenic Model with Flavored Resonant Leptogenesis
Abhishek, V. Suryanarayana Mummidi
We construct a radiative neutrino mass model that combines the scotogenic mechanism with modular flavour symmetry. The entire lepton flavour structure is governed by holomorp…
SIMPonium bound states of complex scalar dark matter: Relic density and astrophysical signatures
Pa. Gokhula Prasad, V. Suryanarayana Mummidi
We study a strongly interacting complex scalar dark matter candidate , subject to an attractive potential mediated by a vector boson . Such interactions allow to form…
Asymmetric dark matter from leptogenesis in type-III seesaw framework with modular symmetry
Abhishek, V. Suryanarayana Mummidi
We present a unified framework for neutrino masses, baryogenesis, and dark matter based on a modular symmetry combined with a type-III seesaw mechanism. All Yukawa couplings,…
Resonant leptogenesis in inverse see-saw framework with modular symmetry
Abhishek, V. Suryanarayana Mummidi
We introduce a lepton mass generation and flavor mixing model, realized through a (2,3) inverse seesaw structure based on modular \( S_4 \) symmetry. The model employs modular form…
Low scale leptogenesis and mixing in neutrinophillic two Higgs doublet model(2HDM) with S4 flavor symmetry
Abhishek, V. Suryanarayana Mummidi
We study a modified version of the Standard Model that includes a scalar doublet and two right-handed neutrinos, forming the neutrinophillic two higgs doublet () fram…
Leptogenesis and fermion mass fit in a renormalizable model
V. Suryanarayana Mummidi, Ketan M. Patel
A non-supersymmetric renormalizable model is investigated for its viability in explaining the observed fermion masses and mixing parameters along with the baryon asymmetry…
Precision unification and Higgsino dark matter in GUT scale supersymmetry
V. Suryanarayana Mummidi, Ketan M. Patel
Even if the concerns related to the naturalness of the electroweak scale are repressed, the Higgs mass and stability of the electroweak vacuum do not allow arbitrarily large supers…
Pseudo-Dirac Higgsino dark matter in GUT scale supersymmetry
V Suryanarayana Mummidi, Ketan M. Patel
We investigate a scenario in which supersymmetry is broken at scale GeV leaving only a pair of Higgs doublets, their superpartners (Higgsinos) and a gauge single…
Effects of heavy neutrinos on vacuum stability in two-Higgs-doublet model with GUT scale supersymmetry
V Suryanarayana Mummidi, Vishnu P. K., Ketan M. Patel
We analyse the implications of right-handed neutrinos on the stability of the electroweak vacuum in two-Higgs-doublet models with supersymmetry at high scale. It is assumed that su…
Higgs mass from neutrino-messenger mixing
Pritibhajan Byakti, Charanjit K Khosa, V. S. Mummidi +1
The discovery of the Higgs particle at 125 GeV has put strong constraints on minimal messenger models of gauge mediation, pushing the stop masses into the multi-TeV regime. Extensi…
Neutralino-Neutralino pair annihilation crosssections with flavour violation
V. Suryanarayana Mummidi
We present the first exact and most general neutralino-neutralino annihilation cross sections in the presence of flavor violation. The existing set of calculations in literature do…
Gravitational rescue of minimal gauge mediation
Abhishek M. Iyer, V Suryanarayana Mummidi, Sudhir K. Vempati
Gravity mediation supersymmetry breaking become comparable to gauge mediated supersymmetry breaking contributions when messenger masses are close to the GUT scale. By suitably tuni…
Anatomy of Higgs mass in Supersymmetric Inverse Seesaw Models
Eung Jin Chun, V. Suryanarayana Mummidi, Sudhir K. Vempati
We compute the one loop corrections to the CP even Higgs mass matrix in the supersymmetric inverse seesaw model to single out the different cases where the radiative corrections fr…
A little more Gauge Mediation and the light Higgs mass
V. Suryanarayana Mummidi, Sudhir K. Vempati
We consider minimal models of gauge mediated supersymmetry breaking with an extra factor in addition to the Standard Model gauge group. A charged, Standard Model sing…
