Zeros of Amplitude in the Associated Production of Photon and Leptoquark at - Collider
Priyotosh Bandyopadhyay, Saunak Dutta, Anirban Karan
Though various extensions of the Standard Model with higher gauge group predict the existence of leptoquarks, none of them has been observed yet at any of the colliders. In this pa…
Relativistic Freeze-in with Scalar Dark Matter in a Gauged Model and Electroweak Symmetry Breaking
Priyotosh Bandyopadhyay, Manimala Mitra, Abhishek Roy
We explore relativistic freeze-in production of scalar dark matter in gauged model, where we focus on the production of dark matter from the decay and annihilation of Standar…
Power corrections to event shapes using eikonal dressed gluon exponentiation
Neelima Agarwal, Ayan Mukhopadhyay, Sourav Pal +1
Event shapes are classical tools for the determination of the strong coupling and for the study of hadronization effects in electron-positron annihilation. In the context of analyt…
Seesaw Models under the Lens of Angular Distributions at and Colliders
Priyotosh Bandyopadhyay, Anirban Karan, Chandrima Sen
The Seesaw extensions of the Standard Model not only provide a natural explanation for tiny neutrino masses, they also predict additional heavy states such as Majorana neutrinos, c…
Obscure Higgs boson at Colliders
Priyotosh Bandyopadhyay, Antonio Costantini
In this study we consider an extension of the Standard Model with a complex hypercharge zero triplet scalar. In this scenario one of the charged Higgs bosons remains purely triplet…
Connecting Low scale Seesaw for Neutrino Mass to Inelastic sub-GeV Dark Matter with Abelian Gauge Symmetry
Debasish Borah, Satyabrata Mahapatra, Narendra Sahu
Motivated by the recently reported excess of electron recoil events by the XENON1T experiment, we propose low scale seesaw scenarios for light neutrino masses within gauge…
Singlet-Doublet Majorana Dark Matter and Neutrino Mass in a minimal Type-I Seesaw Scenario
Manoranjan Dutta, Subhaditya Bhattacharya, Purusottam Ghosh +1
In a bid to simultaneous explanation of dark matter (DM) and tiny but non-zero masses of left-handed neutrinos, we propose a minimal extension of the Standard Model (SM) by a vecto…
Dealing with T and CPT violations in mixing as well as direct and indirect CP violations for neutral mesons decaying to two vectors
Anirban Karan
A large number of observables can be constructed from differential decay rate based on the polarization of final state while considering decay of a neutral meson $(P^0 \text{ or }…
Scrutinizing Vacuum Stability in IDM with Type-III Inverse seesaw
Priyotosh Bandyopadhyay, Shilpa Jangid, Manimala Mitra
We consider the extension of the Standard Model (SM) with an inert Higgs doublet that also contains two or three sets of triplet fermions with hypercharge zero and analyz…
Distinguishing Leptoquarks at the LHC/FCC
Priyotosh Bandyopadhyay, Saunak Dutta, Mahesh Jakkapu +1
In this article, we deal with how to distinguish the signatures of different \LQs at the LHC/FCC if all of them lie within similar mass and coupling range and can be produced at pr…
Inelastic Fermion Dark Matter Origin of XENON1T Excess with Muon and Light Neutrino Mass
Debasish Borah, Satyabrata Mahapatra, Dibyendu Nanda +1
Motivated by the recently reported excess in electron recoil events by the XENON1T collaboration, we propose an inelastic fermion dark matter (DM) scenario within the framework of…
Feeble neutrino portal dark matter at neutrino detectors
Priyotosh Bandyopadhyay, Eung Jin Chun, Rusa Mandal
We explore the neutrino portal dark matter (DM) at its minimum of field content having two dark sector particles coupled to a right-handed neutrino. Assuming the feeble nature of t…
Neutrino Mixing by modifying the Yukawa coupling structure of constrained sequential dominance
Joy Ganguly, Raghavendra Srikanth Hundi
In the constrained sequential dominance (CSD), tri-bimaximal mixing (TBM) pattern in the neutrino sector has been explained, by proposing a certain Yukawa coupling structure for th…
Distinguishing Inert Higgs Doublet and Inert Triplet Scenarios
Shilpa Jangid, Priyotosh Bandyopadhyay
In this article we consider a comparative study between Type-I 2HDM and , triplet extensions having one -odd doublet and triplet that render the desired dark matt…
Investigating the Production of Leptoquarks by Means of Zeros of Amplitude at Photon Electron Collider
Priyotosh Bandyopadhyay, Saunak Dutta, Anirban Karan
Leptoquarks are one of the possible candidates for explaining various anomalies in flavour physics. Nonetheless, their existence is yet to be confirmed from experimental side. In t…
Neutrino masses and mixing angles in a model with six Higgs triplets and symmetry
Raghavendra Srikanth Hundi, Itishree Sethi
We have considered a model \cite{ma-weg}, where masses and a mixing pattern for neutrinos are governed by six Higgs triplets and symmetry. In this model we have applied a cer…
Multiparton webs beyond three loops
Neelima Agarwal, Abhinava Danish, Lorenzo Magnea +2
Correlators of Wilson-line operators are fundamental ingredients for the study of the infrared properties of non-abelian gauge theories. In perturbation theory, they are known to e…
Flavoured CP-asymmetry at the effective neutrino mass floor
Nimmala Narendra, Narendra Sahu, S. Uma Sankar
Both neutrinoless double beta decay and leptogenesis require neutrinos to be Majorana fermions. A relation between these two phenomena can be derived once the mechanism of neutrino…
Verifiable type-II seesaw and dark matter in a gauged model
Satyabrata Mahapatra, Nimmala Narendra, Narendra Sahu
We propose a gauged extension of the standard model (SM) to explain simultaneously the light neutrino masses and dark matter (DM). The generation of neutrino masses oc…
