Constraining Non-thermal and Thermal properties of Dark Matter
P. S. Bhupal Dev, Anupam Mazumdar, Saleh Qutub
We describe the evolution of Dark Matter (DM) abundance from the very onset of its creation from inflaton decay under the assumption of an instantaneous reheating. Based on the ini…
Probing TeV Left-Right Seesaw at Energy and Intensity Frontiers: a Snowmass White Paper
P. S. Bhupal Dev, R. N. Mohapatra
We discuss ways to probe the origin of neutrino masses at the Energy and Intensity frontiers, in TeV-scale left-right seesaw models where small neutrino masses arise via type-I see…
Standard Model Explanation of the Ultra-high Energy Neutrino Events at IceCube
Chien-Yi Chen, P. S. Bhupal Dev, Amarjit Soni
The recent observation of two PeV events at IceCube, followed by an additional 26 events between 30 - 300 TeV, has generated considerable speculations on its origin, and many exoti…
Natural TeV-Scale Left-Right Seesaw for Neutrinos and Experimental Tests
P. S. Bhupal Dev, Chang-Hun Lee, R. N. Mohapatra
We present a TeV-scale left-right ultraviolet completion of type-I seesaw for neutrino masses based on the gauge group without parity, whic…
New Production Mechanism for Heavy Neutrinos at the LHC
P. S. Bhupal Dev, Apostolos Pilaftsis, Un-ki Yang
We study a new production mechanism for heavy neutrinos at the LHC, which dominates over the usually considered -channel -exchange diagram for heavy-neutrino masses larger th…
Neutrino Mass and Dark Matter in light of recent AMS-02 results
P. S. Bhupal Dev, Dilip Kumar Ghosh, Nobuchika Okada +1
We study a simple extension of the Standard Model supplemented by an electroweak triplet scalar field to accommodate small neutrino masses by the type-II seesaw mechanism, while an…
Probing Heavy-Light Neutrino Mixing in Left-Right Seesaw Models at the LHC
Chien-Yi Chen, P. S. Bhupal Dev, R. N. Mohapatra
We show that in TeV-scale left-right (L-R) symmetric seesaw models, there are new dominant contributions to the collider signals of heavy Majorana neutrinos arising from the heavy-…
Invisible Higgs Decay in a Supersymmetric Inverse Seesaw Model with Light Sneutrino Dark Matter
Shankha Banerjee, P. S. Bhupal Dev, Subhadeep Mondal +2
Within the framework of a constrained Minimal Supersymmetric Standard Model (cMSSM) augmented by an MSSM singlet-pair sector to account for the non-zero neutrino masses by inverse…
Constraining Neutrino Mass from Neutrinoless Double Beta Decay
P. S. Bhupal Dev, Srubabati Goswami, Manimala Mitra +1
We re-analyze the compatibility of the claimed observation of neutrinoless double beta decay () in Ge with the new limits on the half-life of Xe from EXO-200 a…
Post-Sphaleron Baryogenesis and an Upper Limit on the Neutron-Antineutron Oscillation Time
K. S. Babu, P. S. Bhupal Dev, Elaine C. F. S. Fortes +1
A recently proposed scenario for baryogenesis, called post--sphaleron baryogenesis (PSB) is discussed within a class of quark--lepton unified framework based on the gauge symmetry…
Naturalness of Light Neutralino Dark Matter in pMSSM after LHC, XENON100 and Planck Data
Celine Boehm, P. S. Bhupal Dev, Anupam Mazumdar +1
We examine the possibility of a light (below 46 GeV) neutralino dark matter (DM) candidate within the 19-parameter phenomenological Minimal Supersymmetric Standard Model (pMSSM) in…
125 GeV Higgs Boson and the Type-II Seesaw Model
P. S. Bhupal Dev, Dilip Kumar Ghosh, Nobuchika Okada +1
We study the vacuum stability and unitarity conditions for a 125 GeV Standard Model (SM)-like Higgs boson mass in the type-II seesaw model. We find that, as long as the seesaw scal…
