Leptogenesis and eV scale sterile neutrino
Srubabati Goswami, Vishnudath K. N., Ananya Mukherjee +1
We consider the minimal extended seesaw model which can accommodate an eV scale sterile neutrino. The scenario also includes three heavy right handed neutrinos in addition to the l…
Custodial symmetry, Georgi-Machacek model, and other scalar extensions
Anirban Kundu, Poulami Mondal, Palash B. Pal
In an SU(2) gauge theory, if the gauge bosons turn out to be degenerate after spontaneous symmetry breaking, obviously these mass terms are invariant under a global SU(2) symmetry…
Measuring violating phase in beauty baryon decays
Rahul Sinha, Shibasis Roy, N. G. Deshpande
One of the outstanding problems in physics is to explain the baryon-anti-baryon asymmetry observed in nature. According to the well-known Sakharov criterion for explaining the obse…
Testing left-right symmetry with an inverse seesaw mechanism at the LHC
Mathew Thomas Arun, Tanumoy Mandal, Subhadip Mitra +3
In the left-right symmetric models, a heavy charged gauge boson can decay to a lepton and a right-handed neutrino (RHN). If the neutrino masses are generated through the stand…
Phenomenology of an inspired extension of Standard Model: Higgs sector
Sanchari Bhattacharyya, Anindya Datta
We investigate a variant of Left-Right symmetric model based on inspired gauge group . Sponta…
Following the trail of new physics via VBF Higgs signal at the Large Hadron Collider
Tisa Biswas, Anindya Datta, Biswarup Mukhopadhyaya
We investigate the modification of the Higgs signals from vector boson fusion at the LHC arising from higher-dimensional effective operators involving quarks, electroweak gauge bos…
