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…

Reinterpretation and preservation of data and analyses in HEP

Jon Butterworth, Sabine Kraml, Harrison Prosper +145

Data from particle physics experiments are unique and are often the result of a very large investment of resources. Given the potential scientific impact of these data, which goes…

On the Robustness of type-II Seesaw Collider Searches

Christoph Englert, Manimala Mitra, Wrishik Naskar +1

Electroweak triplet Higgs sector extensions are well-motivated scenarios to address lepton flavour observations. These models can also be strongly constrained by combining precise,…

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…

Differentiating Dimension-6 and Dimension-8 Effects in SMEFT at the HL-LHC

Manimala Mitra, Shakeel Ur Rahaman, Subham Saha +1

We study dimension-eight effects in the Standard Model Effective Field Theory extended by right-handed neutrinos (SMEFT). Using the Hilbert series formalism, we derive the comp…

Complex scalar dark matter with effective Higgs portals beyond radiation domination

Manimala Mitra, Dipankar Pradhan, Subham Saha

The increasingly stringent bounds on the Higgs-portal coupling, arising from dark matter (DM) direct-detection searches, confront the minimal renormalizable complex scalar DM scena…
