One Event, Two Frontiers: From LZ to LHC
Md Sadique Anwar, Nivedita Ghosh, Sahabub Jahedi +1
The 248 keV nuclear-recoil event observed by the LUX-ZEPLIN (LZ) experiment could potentially arise from dark matter (DM) interactions with nucleons. We investigate elastic scatter…
Chasing Long-Lived Doubly Charged Scalars at Future Lepton Colliders
Nandini Das, Dilip Kumar Ghosh, Nivedita Ghosh +1
We come up with a novel search strategy for long-lived doubly charged scalars at future proposed lepton colliders. The doubly charged scalar studied in this work belongs to an $SU(…
Investigating the leptonic couplings of doubly charged scalars at the muon collider
Nivedita Ghosh, Santosh Kumar Rai, Tousik Samui +1
We study the lepton flavour conserving and violating couplings of a doubly charged scalar at a 3 TeV muon collider. Using a model independent Lagrangian, we analyse the electron el…
Unveiling the CP-odd Higgs in a Generalized 2HDM at a Muon Collider
Nandini Das, Nivedita Ghosh
We revisit the generalized two-Higgs-doublet model (2HDM) with a minimally perturbed lepton specific (Type-X) Yukawa sector in context of the muon collider. The model offers a larg…
Search For a Leptoquark and Vector-like Lepton in a Muon Collider
Nivedita Ghosh, Santosh Kumar Rai, Tousik Samui
The proposal for a high-energy muon collider offers many opportunities in the search for physics beyond the Standard Model (BSM). The collider by construction is likely to be more…
New physics implications of VBF searches exemplified through the Georgi-Machacek model
Manimala Chakraborti, Dipankar Das, Nivedita Ghosh +2
LHC searches for nonstandard scalars in vector boson fusion (VBF) production processes can be particularly efficient in probing scalars belonging to triplet or higher multiplet rep…
Light long-lived particles at the FCC-hh with the proposal for a dedicated forward detector FOREHUNT and a transverse detector DELIGHT
Biplob Bhattacherjee, Herbi K. Dreiner, Nivedita Ghosh +3
In this paper, we propose a dedicated forward detector, FOREHUNT (FORward~Experiment~for~HUNdred~TeV), for 100 TeV FCC-hh for the detection of light long-lived particles (LLP) comi…
Collider Signatures of a Scalar Leptoquark and Vector-like Lepton in Light of Muon Anomaly
Nivedita Ghosh, Santosh Kumar Rai, Tousik Samui
Despite the immense success of the Standard Model, the hunt for physics beyond the Standard Model has continued. Extension of the SM gauge group or the particle content of the SM r…
Signals for vector-like leptons in an -symmetric 2HDM at ILC
Indrani Chakraborty, Dilip Kumar Ghosh, Nivedita Ghosh +1
In this work, we explore the signals of an -symmetric two Higgs doublet model with two generations of vector-like leptons (VLLs) at the proposed International Linear Collider…
Dark Matter and Collider Searches in -Symmetric 2HDM with Vector Like Leptons
Indrani Chakraborty, Dilip Kumar Ghosh, Nivedita Ghosh +1
We study the -symmetric two Higgs doublet model by adding two generations of vector like leptons (VLL) which are odd under a discrete symmetry. The lightest neutral comp…
Generalized 2HDM with wrong-sign lepton Yukawa coupling, in light of and lepton flavor violation at the future LHC
Nivedita Ghosh, Jayita Lahiri
To explain the observed muon anomaly and simultaneously evade bounds from lepton flavor violation in the same model parameter space is a long cherished dream. In view of a generali…
Revisiting Generalized Two Higgs Doublet Model in the Light of Muon Anomaly and Lepton Flavor Violating Decays at HL-LHC
Nivedita Ghosh, Jayita Lahiri
One of the main motivations to look beyond the SM is the discrepancy between the theoretical prediction and observation of anomalous magnetic moment of muon. Alleviating this tensi…
Associated production in the flavorful scenario for
Siddharth Dwivedi, Adam Falkowski, Dilip Kumar Ghosh +1
The flavorful model with its couplings restricted to the left-handed second generation leptons and third generation quarks can potentially resolve the observed anomalies…
Charged Higgs searches in the Georgi-Machacek model at the LHC
Nivedita Ghosh, Swagata Ghosh, Ipsita Saha
The Georgi-Machacek Model allows for a large triplet vacuum expectation value (vev) with a custodial symmetric scalar potential. This manifestly leads to large charged Higgs coupli…
Collider signature of Leptoquark and constraints from observables
Aritra Biswas, Dilip Kumar Ghosh, Nivedita Ghosh +2
One of the most popular models that is known to be able to solve the lepton flavour universality violating charged () and neutral current () anomalies is the Leptoq…
Distinctive Collider Signals for a Two Higgs Triplet Model
Dilip Kumar Ghosh, Nivedita Ghosh, Biswarup Mukhopadhyaya
The extension of the Standard Model (SM) with two complex scalar triplets enables one to have the Type II seesaw mechanism operative consistently with texture-zero neut…
Revisiting the high-scale validity of Type-II seesaw model with novel LHC signature
Dilip Kumar Ghosh, Nivedita Ghosh, Ipsita Saha +1
The Type-II seesaw model is a well-motivated new physics scenario to address the origin of the neutrino mass issue. We show that this model can easily accommodate an absolutely sta…
Dark Matter and Collider Studies in the Left-Right Symmetric Model with Vector-Like Leptons
