Belle II Constraints on the Non-Minimal Universal Extra Dimensional Model
Avirup Shaw
Recent measurements by the Belle II Collaboration report a branching ratio for the decay with a 3.5 significance and deviating by 2.7 from Standard Model…
Neutrino mass and leptogenesis in a hybrid seesaw model with a spontaneously broken CP
Rohan Pramanick, Tirtha Sankar Ray, Avirup Shaw
We introduce a novel hybrid framework combining type I and type II seesaw models for neutrino mass where a complex vacuum expectation value of a singlet scalar field breaks CP spon…
Reappraisal of the minimal flavoured scenario
Tirtha Sankar Ray, Avirup Shaw
Recent results from the intensity frontier indicate the tantalizing possibility of violation in lepton flavour universality. In light of this we revisit the minimal phenomenologica…
The impact of nonminimal Universal Extra Dimensional model on transitions
Avirup Shaw
We measure the impact of nonvanishing boundary localised terms on transitions in five-dimensional Universal Extra Dimensional scenario where masses and coupling strengths of…
Looking for in non-minimal Universal Extra Dimensional model
Avirup Shaw
Non-vanishing boundary localised terms significantly modify the mass spectrum and various interactions among the Kaluza-Klein excited states of 5-Dimensional Universal Extra Dimens…
Reconciling dark matter, anomalies and in an scenario
Anirban Biswas, Avirup Shaw
We propose an anomaly free unified scenario by invocation of an extra local gauge symmetry. This scenario simultaneously resolves the anomalies…
Collider signature of Leptoquark with flavour observables
Aritra Biswas, Avirup Shaw, Abhaya Kumar Swain
The Leptoquark model has been instrumental in explaining the observed lepton flavour universality violating charged () and neutral () current anomalies that have be…
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…
anomalies in light of extended scalar sectors
Aritra Biswas, Dilip Kumar Ghosh, Sunando Kumar Patra +1
Considering the recent experimental results on exclusive semileptonic meson decays showing sizable departure from their Standard Model prediction of lepton flavor universality…
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…
Status of exclusion limits of the KK-parity non-conserving resonance production with updated 13 TeV LHC
Avirup Shaw
Unequal strengths of boundary localised terms lead to non-conservation of the Kaluza-Klein (KK) parity in the 4 + 1 Universal Extra Dimensional model. Consequently the first excite…
Explaining Dark Matter and Neutrino Mass in the light of TYPE-II Seesaw Model
Anirban Biswas, Avirup Shaw
With the motivation of simultaneously explaining dark matter and neutrino masses, mixing angles, we have invoked the Type-II seesaw model extended by an extra doublet .…

Aritra Biswas, Sunando Kumar Patra, Avirup Shaw
We estimate contributions from Kaluza-Klein excitations of gauge bosons and physical charge scalar for the explanation of the lepton flavor universality violating excess in the rat…

We estimate contributions from Kaluza-Klein excitations of third generation quarks and gauge bosons to the branching ratio of decay process in 5-Dimensional Uni…
Exploring the extended scalar sector with resonances in vector boson scattering
Najimuddin Khan, Biswarup Mukhopadhyaya, Subhendu Rakshit +1
We show that the study of scalar resonances at various vector boson scattering processes at the Large Hadron Collider can serve as a useful tool to distinguish between different ex…
Non-minimal UED confronts
Anindya Datta, Avirup Shaw
Addition of boundary localised kinetic and Yukawa terms to the action of a 5-dimensional Standard Model would non-trivially modify the Kaluza-Klein spectra and some of the interact…
A note on gauge-fixing in the electroweak sector of nmUED
Anindya Datta, Avirup Shaw
Electroweak observables are highly sensitive to the loop corrections. Therefore, a proper gauge-fixing mechanism is always needed to define the propagators which are involved in Fe…
KK-parity non-conservation in UED confronts LHC data

Kaluza-Klein (KK) parity can be violated in five-dimensional universal extra dimensional model with boundary-localized (kinetic or mass) terms (BLTs) at the fixed points of $S^1/Z_…
Universal Extra-Dimensional models with boundary terms: Probing at the LHC

In universal extra-dimensional models a conserved Z_2 parity stabilizes the lightest Kaluza-Klein particle, a dark-matter candidate. Boundary-localized kinetic terms, in general, d…

Anindya Datta, Amitava Raychaudhuri, Avirup Shaw
In five-dimensional universal extra-dimensional models compactified on an orbifold four-dimensional kinetic terms are allowed at the two fixed points. If these terms are…
