Tagging fully hadronic exotic decays of the vectorlike quark using a graph neural network
Jai Bardhan, Tanumoy Mandal, Subhadip Mitra +2
Following up on our earlier study in [J. Bardhan et al., Machine learning-enhanced search for a vectorlike singlet B quark decaying to a singlet scalar or pseudoscalar, Phys. Rev.…
Machine learning tagged boosted dark photon: A signature of fermionic portal matter at the LHC
Shivam Verma, Sanjoy Biswas, Tanumoy Mandal +1
We use a Hybrid Deep Neural Network (HDNN) to identify a boosted dark photon jet as a signature of a heavy vector-like fermionic portal matter (PM) connecting the visible and the d…
Vector leptoquark contributions to lepton dipole moments
Arvind Bhaskar, Diganta Das, Soumyadip Kundu +3
Leptoquarks (LQs) can contribute to the magnetic and electric dipole moments of charged leptons, which the current experiments have measured with good accuracy. We revisit the para…
Unsupervised and lightly supervised learning in particle physics
Jai Bardhan, Tanumoy Mandal, Subhadip Mitra +2
We review the main applications of machine learning models that are not fully supervised in particle physics, i.e., clustering, anomaly detection, detector simulation, and unfoldin…
Fresh look at the LHC limits on scalar leptoquarks
Arvind Bhaskar, Arijit Das, Tanumoy Mandal +2
The scalar-leptoquark (sLQ) parameter space is well explored experimentally. The direct pair production searches at the LHC have excluded light sLQs almost model agnostically, and…
Pinning down the leptophobic in leptonic final states with Deep Learning
Tanumoy Mandal, Aniket Masaye, Subhadip Mitra +3
A leptophobic that does not couple with the Standard Model leptons can evade the stringent bounds from the dilepton-resonance searches. In our earlier paper [T. Arun et…
Right-handed neutrino pair production via second-generation leptoquarks
Arvind Bhaskar, Yash Chaurasia, Kuldeep Deka +3
No direct experimental constraints exist on Leptoquark (LQ) couplings with quarks and right-handed neutrinos (RHNs). If a LQ dominantly couples to RHNs, it can leave unique signatu…
Machine learning-enhanced search for a vectorlike singlet quark decaying to a singlet scalar or pseudoscalar
Jai Bardhan, Tanumoy Mandal, Subhadip Mitra +1
The presence of a new decay mode relaxes the current mass exclusion limits on vectorlike quarks considerably. We consider the case of a weak-singlet vectorlike quark that can d…

Diganta Das, Jaydeb Das, Girish Kumar +1
We investigate the possible sizes of all the CP-violating asymmetries offered by the angular distribution of rare decay in the Standard M…
Production of Singlet dominated scalar(s) at the LHC
Subhadip Bisal, Debottam Das, Swapan Majhi +1
The leading order production of an SM singlet-like scalar has primarily been realized through the gluon fusion process by mixing with the scalar doublet of the model. The…
Renormalization group improved and determination from hadronic decays
B. Ananthanarayan, Diganta Das, M. S. A. Alam Khan
We determine the strange quark mass () and quark mixing element , and their joint determination from the Cabibbo suppressed hadronic decays in various…
Leptoquark-assisted Singlet-mediated Di-Higgs Production at the LHC
Arvind Bhaskar, Debottam Das, Bibhabasu De +3
At the LHC, the gluon-initiated processes are considered to be the primary source of di-Higgs production. However, in the presence of a new resonance, the light-quark initiated pro…
Combined explanation of -mass, muon , and anomalies in a singlet-triplet scalar leptoquark model
Arvind Bhaskar, Anirudhan A. Madathil, Tanumoy Mandal +1
In addition to the long-standing anomalies seen in the muon , , and observables by various independent experiments, the CDF Collaboration has found…
Discovery prospects of a vectorlike top partner decaying to a singlet boson
Akanksha Bhardwaj, Kartik Bhide, Tanumoy Mandal +2
The possibility of a vectorlike top partner decaying to a new colourless weak-singlet scalar or pseudoscalar has attracted some attention in the literature. We investigate the prod…
Search for the boson decaying to a right-handed neutrino pair in leptophobic models
Mathew Thomas Arun, Arpan Chatterjee, Tanumoy Mandal +3
The extensions of the Standard Model contain a heavy neutral gauge boson . If leptophobic, the boson can evade the stringent bounds from the dilepton resonance sea…
Roadmap to explore vectorlike quarks decaying to a new scalar or pseudoscalar
Akanksha Bhardwaj, Tanumoy Mandal, Subhadip Mitra +1
The current experimental data allow for a sub-TeV colourless weak-singlet scalar or pseudoscalar. If such a singlet field is present together with TeV-range vectorlike top and bott…
Precise LHC limits on the leptoquark parameter space
Arvind Bhaskar, Diganta Das, Tanumoy Mandal +2
A TeV scale leptoquark (LQ) is one of the promising explanations of the recent anomalies in the semileptonic decays of mesons. Among the various LQs, the vector is c…
Sterile neutrinos in decays
Diganta Das, Jaydeb Das
We study lepton number violating and lepton number conserving semi-leptonic decays of heavy baryons to three charged leptons and a neutrino. The decays occur through two in…
Testing left-right symmetry with an inverse seesaw mechanism at the LHC
Mathew Thomas Arun, Tanumoy Mandal, Subhadip Mitra +3
In the left-right symmetric models, a heavy charged gauge boson can decay to a lepton and a right-handed neutrino (RHN). If the neutrino masses are generated through the stand…
Improving third-generation leptoquark searches with combined signals and boosted top
Arvind Bhaskar, Tanumoy Mandal, Subhadip Mitra +1
Search strategies for the third-generation leptoquarks (LQs) are distinct from other LQ searches, especially when they decay to a top quark and a lepton. We investigate the cas…

Arvind Bhaskar, Diganta Das, Tanumoy Mandal +2
The leptoquark is known to be a suitable candidate for explaining the semileptonic -decay anomalies. We derive precise limits on its parameter space relevant for the anoma…
Cancellation in Dark Matter-Nucleon Interactions: the Role of Non-Standard-Model-like Yukawa Couplings
Debottam Das, Bibhabasu De, Subhadip Mitra
Extensive searches to probe the particle nature of dark matter (DM) have been going on for some decades now but, so far, no conclusive evidence has been found. Among various option…
