Exploring Leptoquarks and Majorana Neutrinos via same-sign dimuons at the HL-LHC

Subham Saha, Arvind Bhaskar, Manimala Mitra

We study the phenomenology of scalar leptoquark (sLQ) coupled to right-handed neutrinos (RHNs) at the High-Luminosity Large Hadron Collider (HL-LHC), focusing on…

Exploring Scalar Leptoquarks at Muon Collider via Indirect Signatures and Right-Handed Neutrino-Assisted Decays

Subham Saha, Arvind Bhaskar, P. S. Bhupal Dev +1

Scalar leptoquarks (sLQs) appear in a wide range of ultraviolet-motivated extensions of the Standard Model and provide a natural link between the quark and lepton sectors. In this…

TooLQit: Leptoquark Models and Limits

Arvind Bhaskar, Yash Chaurasia, Arijit Das +5

We introduce the leptoquark (LQ) toolkit, TooLQit, which includes leading-order FeynRules models for all types of LQs and a Python-based calculator, named CaLQ, to test if a set of…

Boosted top quark inspired leptoquark searches at the muon collider

Arvind Bhaskar, Manimala Mitra

The proposed muon collider presents a promising avenue to explore various classes of beyond the Standard Model (BSM) particles. In this paper, we investigate the discovery prospect…

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…

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…

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…

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…

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…

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…

LHC Bounds on motivated Leptoquark Models

Arvind Bhaskar, Tanumoy Mandal, Subhadip Mitra +2

Most of the popular explanations of the observed anomalies in the semileptonic -meson decays involve TeV scale Leptoquarks (LQs). Among the various possible LQ models, two parti…

Precise limits on the charge- vector leptoquark

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…

Boosting vector leptoquark searches with boosted tops

Arvind Bhaskar, Tanumoy Mandal, Subhadip Mitra

At the LHC, a TeV-scale leptoquark (LQ) that decays dominantly to a top quark () and a light charged lepton () would form a resonance system of \emph{boosted- h…

Enhancing Scalar Productions with Leptoquarks at the LHC

Arvind Bhaskar, Debottam Das, Bibhabasu De +1

The Standard Model (SM), when extended with a leptoquark (LQ) and right-handed neutrinos, can have interesting new implications for Higgs physics. We show that sterile neutrinos ca…

Effective gravitational mass of the Ayón-Beato and Garc\'ıa metric

A. K. Sinha, G. K. Pandey, A. K. Bhaskar +4

In this paper, we calculate the effective gravitational mass of Ayón-Beato and Garc\'ıa regular (non-singular) static spherically symmetric asymptotically Minkowskian metric that i…
