Electroweak Symmetry Breaking and WIMP-FIMP Dark Matter
Subhaditya Bhattacharya, Sreemanti Chakraborti, Dipankar Pradhan
Electroweak Symmetry Breaking (EWSB) is known to produce a massive universe that we live in. However, it may also provide an important boundary for freeze-in or freeze-out of dark…
Effective Leptophilic WIMPs at the collider
Basabendu Barman, Subhaditya Bhattacharya, Sudhakantha Girmohanta +1
We consider higher-dimensional effective (EFT) operators consisting of fermion dark matter (DM) connecting to Standard Model (SM) leptons upto dimension six. Considering all operat…
Majorana Dark Matter and Neutrino mass in a singlet-doublet extension of the Standard Model
Manoranjan Dutta, Subhaditya Bhattacharya, Purusottam Ghosh +1
A minimal extension of the Standard Model (SM) by a vector-like fermion doublet and three right handed (RH) singlet neutrinos is proposed in order to explain dark matter and tiny n…
Probing heavy charged fermions at collider using the Optimal Observable Technique
Subhaditya Bhattacharya, Sahabub Jahedi, Jose Wudka
In this work we study the production of color-neutral and singly-charged heavy leptons at the proposed International Linear Collider. We use the optimal observable technique to det…
Symmetry origin of Baryon Asymmetry, Dark Matter and Neutrino Mass
Subhaditya Bhattacharya, Rishav Roshan, Arunansu Sil +1
We propose a minimal model based on lepton number symmetry (and violation), to address a common origin of baryon asymmetry, dark matter and neutrino mass generation. The model cons…
Effective Theories with Dark Matter Applications
Subhaditya Bhattacharya, Jose Wudka
Standard Model (SM) of particle physics has achieved enormous success in describing the interactions among the known fundamental constituents of nature, yet it fails to describe ph…
