Quark Seesaw, Vectorlike Fermions and Diphoton Excess
P. S. Bhupal Dev, Rabindra N. Mohapatra, Yongchao Zhang
We present a possible interpretation of the recent diphoton excess reported by the TeV LHC data in quark seesaw left-right models with vectorlike fermions proposed to…
Di-photon Excess Explained by a Resonant Sneutrino in R-parity Violating Supersymmetry
B. C. Allanach, P. S. Bhupal Dev, S. A. Renner +1
We explain the recent excess seen by ATLAS and CMS experiments at around 750 GeV in the di-photon invariant mass as a narrow width sneutrino decaying to di-photons via a stau loop…
Asymmetric Dark Matter in the Sun and the Diphoton Excess at the LHC
P. S. Bhupal Dev, Daniele Teresi
It has been recently pointed out that a momentum-dependent coupling of the asymmetric Dark Matter (ADM) with nucleons can explain the broad disagreement between helioseismological…
The Scalar Triplet Contribution to Lepton Flavour Violation and Neutrinoless Double Beta Decay in Left-Right Symmetric Model
Gulab Bambhaniya, P. S. Bhupal Dev, Srubabati Goswami +1
We analyse in detail the scalar triplet contribution to the low-energy lepton flavour violating (LFV) and lepton number violating (LNV) processes within a TeV-scale left-right symm…
Looking for New Naturally Aligned Higgs Doublets at the LHC
P. S. Bhupal Dev, Apostolos Pilaftsis
Since the current LHC Higgs data suggest the couplings of the observed 125 GeV Higgs boson to be close to the Standard Model (SM) expectations, any extended Higgs sector must lead…
The ATLAS Di-boson Excess Could Be an R-parity Violating Di-smuon Excess
B. C. Allanach, P. S. Bhupal Dev, Kazuki Sakurai
We propose a new possible explanation of the ATLAS di-boson excess: that it is due to heavy resonant slepton production, followed by decay into di-smuons. The smuon has a mass not…
Disambiguating Seesaw Models using Invariant Mass Variables at Hadron Colliders
P. S. Bhupal Dev, Doojin Kim, Rabindra N. Mohapatra
We propose ways to distinguish between different mechanisms behind the collider signals of TeV-scale seesaw models for neutrino masses using kinematic endpoints of invariant mass v…
Implications of the Diboson Excess for Neutrinoless Double Beta Decay and Lepton Flavor Violation in TeV Scale Left Right Symmetric Model
Ram Lal Awasthi, P. S. Bhupal Dev, Manimala Mitra
Inspired by the recent diboson excess observed at the LHC and possible interpretation within a TeV-scale Left-Right symmetric framework, we explore its implications for low-energy…
Unified explanation of the , diboson and dijet resonances at the LHC
P. S. Bhupal Dev, R. N. Mohapatra
We show that the excess events observed in a number of recent LHC resonance searches can be simultaneously explained within a minimal non-supersymmetric left-right inverse seesaw m…
A facility to Search for Hidden Particles at the CERN SPS: the SHiP physics case
Sergey Alekhin, Wolfgang Altmannshofer, Takehiko Asaka +82
This paper describes the physics case for a new fixed target facility at CERN SPS. The SHiP (Search for Hidden Particles) experiment is intended to hunt for new physics in the larg…
A TeV Scale Model for Baryon and Lepton Number Violation and Resonant Baryogenesis
P. S. Bhupal Dev, Rabindra N. Mohapatra
A simple TeV scale model for baryon and lepton number violation is presented, where neutrino mass arises via a one-loop radiative seesaw effect and B-violation obeys selecti…
Natural Standard Model Alignment in the Two Higgs Doublet Model
P. S. Bhupal Dev, Apostolos Pilaftsis
The current LHC Higgs data provide strong constraints on possible deviations of the couplings of the observed 125 GeV Higgs boson from the Standard Model (SM) expectations. Therefo…
TeV Scale Lepton Number Violation and Baryogenesis
P. S. Bhupal Dev, Chang-Hun Lee, R. N. Mohapatra
Contrary to the common lore based on naive dimensional analysis, the seesaw scale for neutrino masses can be naturally in the TeV range, with small parameters coming from radiative…
Prospects of Heavy Neutrino Searches at Future Lepton Colliders
Shankha Banerjee, P. S. Bhupal Dev, Alejandro Ibarra +2
We discuss the future prospects of heavy neutrino searches at next generation lepton colliders. In particular, we focus on the planned electron-positron colliders, operating in two…
Flavour effects in Resonant Leptogenesis from semi-classical and Kadanoff-Baym approaches
P. S. Bhupal Dev, Peter Millington, Apostolos Pilaftsis +1
Flavour effects play an important role in the statistical evolution of particle number densities in several particle physics phenomena. We present a fully flavour-covariant formali…
Neutrinos and Collider Physics
Frank F. Deppisch, P. S. Bhupal Dev, Apostolos Pilaftsis
We review the collider phenomenology of neutrino physics and the synergetic aspects at energy, intensity and cosmic frontiers to test the new physics behind the neutrino mass mecha…
