Scalar Dark Matter and Radiative Dirac neutrino mass in an extended model
Subhasmita Mishra, Nimmala Narendra, Prafulla Kumar Panda +1
We explore a gauged extension of standard model with inclusion of three right-handed neutrinos of exotic charges to cancel the gauge anomaly. Non-trivial transfo…
Magnetic Moments of Leptons, Charged Lepton Flavor Violations and Dark Matter Phenomenology of a Minimal Radiative Dirac Neutrino Mass Model
Bibhabasu De, Debottam Das, Manimala Mitra +1
In a simple extension of the standard model (SM), a pair of vector like lepton doublets ( and ) and a scalar doublet () have been introduced to help in accom…
Leptogenesis in an extended seesaw model with symmetry
Ujjal Kumar Dey, Tapoja Jha, Ananya Mukherjee +1
We have explored an extended seesaw model accommodating a keV sterile neutrino adopting symmetry. This model provides a natural platform for achieving resonant leptoge…
A Mini-review on Vector-like Leptonic Dark Matter, Neutrino Mass and Collider Signatures
Subhaditya Bhattacharya, Purusottam Ghosh, Nirakar Sahoo +1
We review a class of models in which the Standard Model (SM) is augmented by vector-like leptons: one doublet and a singlet, which are odd under an unbroken discrete symmetry…
Dark matter assisted Dirac leptogenesis and neutrino mass
Nimmala Narendra, Nirakar Sahoo, Narendra Sahu
We propose a minimal extension of the standard model with U(1)_{B-L} \times Z_{2} symmetry. In this model by assuming that the neutrinos are Dirac (i.e. is an exact symmetry)…
Singlet-Doublet Fermionic Dark Matter, Neutrino Mass and Collider Signatures
Subhaditya Bhattacharya, Nirakar Sahoo, Narendra Sahu
We propose a minimal extension of the standard model (SM) by including a scalar triplet with hypercharge 2 and two vector-like leptons: one doublet and a singlet, to explain simula…
