Constraining SMEFT BSM scenarios with EWPO and
Mathew Thomas Arun, Kuldeep Deka, Tripurari Srivastava
Precision observables are well known for constraining most of the Beyond Standard Model (BSM) scenarios tightly. We present here a simple and comprehensive fitting framework for va…
Single-step first order phase transition and gravitational waves in a SIMP dark matter scenario
Nabarun Chakrabarty, Himadri Roy, Tripurari Srivastava
We investigate the non-zero temperature dynamics of a sub-GeV dark matter scenario freezing-out via self-interactions. As a prototype, we take up the case of a scalar dark matter s…
Searches for heavy neutrinos at multi-TeV muon collider : a resonant leptogenesis perspective
Indrani Chakraborty, Himadri Roy, Tripurari Srivastava
In this work, the standard model (SM) is extended with two right-handed (RH) neutrinos and two singlet neutral fermions to yield active neutrino masses via (2,2) inverse see-saw me…
Constraining spinning primordial black holes with global 21-cm signal
Pravin Kumar Natwariya, Alekha C. Nayak, Tripurari Srivastava
We study the upper projected bounds on the dark matter fraction in the form of the primordial black holes (PBHs) with a non-zero spin by using the absorption feature in the global…
Resonant leptogenesis in (2,2) inverse see-saw realisation
Indrani Chakraborty, Himadri Roy, Tripurari Srivastava
In this present work, we uphold the standard model (SM) augmented with two right-handed (RH) neutrinos along with two singlet neutral fermions to generate active neutrino masses vi…
Discriminating the HTM and MLRSM models in collider studies via doubly charged Higgs boson pair production and the subsequent leptonic decays
Janusz Gluza, Magdalena Kordiaczynska, Tripurari Srivastava
We present a case study for the doubly charged Higgs bosons pair production in and colliders with their subsequent decays to four charged leptons. We con…
MeV scale model of SIMP dark matter, neutrino mass and leptogenesis
Subhendra Mohanty, Ayon Patra, Tripurari Srivastava
We consider a simple extension of the Standard Model with two singlet scalar fields and three heavy right-handed neutrinos. One of the scalar fields serves as an MeV scale dark mat…
Roadmap of left-right models based on GUTs
Joydeep Chakrabortty, Rinku Maji, Subhendra Mohanty +2
We perform a detailed study of the grand unified theories and with left-right intermediate gauge symmetries of the form …
Cut and compute: Quick cascades with multiple amplitudes
Joydeep Chakrabortty, Anirban Kundu, Rinku Maji +1
In an earlier paper we have proposed a novel method to compute the decay width for a general cascade decay where the propagators are off-shell and may be of different spin…
Physics at a 100 TeV pp collider: Higgs and EW symmetry breaking studies
R. Contino, D. Curtin, A. Katz +72
This report summarises the physics opportunities for the study of Higgs bosons and the dynamics of electroweak symmetry breaking at the 100 TeV pp collider.
Physics at a 100 TeV pp collider: beyond the Standard Model phenomena
T. Golling, M. Hance, P. Harris +111
This report summarises the physics opportunities in the search and study of physics beyond the Standard Model at a 100 TeV pp collider.
Theoretical constraints on masses of heavy particles in Left-Right Symmetric Models
J. Chakrabortty, J. Gluza, T. Jelinski +1
Left-Right symmetric models with general gauge couplings which include bidoublet and triplet scalar multiplets are studied. Possible scalar mass spectra are outlined…
Novel method to deal with off-shell particles in cascade decays
Joydeep Chakrabortty, Anirban Kundu, Tripurari Srivastava
We propose a novel algorithm to compute the width of any generic -body decay involving multiple off-shell particles having zero and non-zero spins. Starting from a toy example,…
Di-photon resonance around 750 GeV: shedding light on the theory underneath
Joydeep Chakrabortty, Arghya Choudhury, Pradipta Ghosh +2
Both the ATLAS and CMS collaborations have recently observed an excess in the di-photon invariant mass distribution in the vicinity of 750 GeV with a local significance of …
Reconciling and charged lepton flavour violating processes through a doubly charged scalar
Joydeep Chakrabortty, Pradipta Ghosh, Subhadeep Mondal +1
In this work, we investigate the phenomenological consequences of a doubly charged scalar which may belong to different uncoloured scalar multiplets. This doubly charged scalar cou…
