Complex Scalar Dark Matter with a Vector-Like Quark and Lepton: Precision, Flavor, and HL-LHC
Lipika Kolay, Rusa Mandal, Manimala Mitra +2
We investigate a minimal extension of the SM consisting of a -stabilized complex scalar dark matter (CSDM) candidate, a down-type vector-like quark (VLQ), and a charg…
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 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…
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 compl…
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…
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…
