Right-handed neutrino production through first-generation leptoquarks
Gokul Duraikandan, Rishabh Khanna, Tanumoy Mandal +2
The collider phenomenology of leptoquarks (LQs) and right-handed neutrinos (RHNs) has been studied extensively in the literature. Because of the gauge singlet nature, the productio…
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…
Neutrino and phenomenology in an anomaly-free extension: role of higher-dimensional operators
Debajyoti Choudhury, Kuldeep Deka, Tanumoy Mandal +1
We consider an anomaly-free extension of the Standard Model with three right-handed neutrinos (RHNs) and two complex scalars, wherein the charge assignments preclud…
Hunting scalar leptoquarks with boosted tops and light leptons
Kushagra Chandak, Tanumoy Mandal, Subhadip Mitra
The LHC search strategies for leptoquarks that couple dominantly to a top quark are different than for the ones that couple mostly to the light quarks. We consider charge ($ϕ…
