Phase transition and gravitational waves in maximally symmetric composite Higgs model
Avik Banerjee, Marco Merchand, Ignacy Nałęcz
In this paper we study phase transitions in a maximally symmetric composite Higgs model with next-to-minimal coset, where a pseudoscalar singlet emerges alongside the Higgs doublet…
Vector-like quarks: status and new directions at the LHC
Avik Banerjee, Elin Bergeaas Kuutmann, Venugopal Ellajosyula +3
Experimental searches for vector-like quarks have until now only considered their decays into Standard Model particles. However, various new physics scenarios predict additional sc…
Nambu-Goto equation from three-dimensional gravity
Avik Banerjee, Ayan Mukhopadhyay, Giuseppe Policastro
We demonstrate that the solutions of three-dimensional gravity obtained by gluing two copies of a spacetime across a junction constituted of a tensile string are in one-to-one corr…
Heavy vector-like quarks decaying to exotic scalars: a case study with triplets
Avik Banerjee, Venugopal Ellajosyula, Luca Panizzi
We investigate the pair production of a vector-like quark triplet with hypercharge 5/3 decaying into top quark and a complex scalar triplet with hypercharge 1 at the LHC. This nove…
How Gubser flow ends in a holographic conformal theory
Avik Banerjee, Toshali Mitra, Ayan Mukhopadhyay +1
Gubser flow is an axis-symmetric and boost-invariant evolution in a relativistic quantum field theory which is best studied by mapping to $dS_{3}\times \mathbf{R…
Vacuum misalignment in presence of four-Fermi operators
Avik Banerjee, Gabriele Ferretti
We consider the issue of vacuum misalignment induced by four-Fermi couplings in a generic strongly coupled four-dimensional gauge theory. After briefly reviewing the general formal…
Report of the Topical Group on Physics Beyond the Standard Model at Energy Frontier for Snowmass 2021
Tulika Bose, Antonio Boveia, Caterina Doglioni +318
This is the Snowmass2021 Energy Frontier (EF) Beyond the Standard Model (BSM) report. It combines the EF topical group reports of EF08 (Model-specific explorations), EF09 (More gen…
TF08 Snowmass Report: BSM Model Building
Patrick J. Fox, Graham D. Kribs, Hitoshi Murayama +53
We summarize the state of Beyond the Standard Model (BSM) model building in particle physics for Snowmass 2021, focusing mainly on several whitepaper contributions to BSM model bui…
Correlation functions of the Bjorken flow in the holographic Schwinger-Keldysh approach
Avik Banerjee, Toshali Mitra, Ayan Mukhopadhyay
One of the outstanding problems in the holographic approach to many-body physics is the explicit computation of correlation functions in nonequilibrium states. We provide a new and…
Fingerprints of freeze-in dark matter in an early matter-dominated era
Avik Banerjee, Debtosh Chowdhury
We study the impact of an alternate cosmological history with an early matter-dominated epoch on the freeze-in production of dark matter. Such early matter domination is triggered…
Phenomenological aspects of composite Higgs scenarios: exotic scalars and vector-like quarks
Avik Banerjee, Diogo Buarque Franzosi, Giacomo Cacciapaglia +8
Composite Higgs models usually contain additional pseudo Nambu Goldstone bosons and vector-like quarks. We discuss various aspects related to their LHC phenomenology and provide su…
Probing composite Higgs boson substructure at the HL-LHC
Avik Banerjee, Sayan Dasgupta, Tirtha Sankar Ray
The Higgs boson may well be a composite scalar with a finite extension in space. Owing to the momentum dependence of its couplings the imprints of such a composite pseudo Goldstone…
