Axion Paradigm with Color-Mediated Neutrino Masses
A. Batra, H. B. Câmara, F. R. Joaquim +2
We propose a generalized Kim-Shifman-Vainshtein-Zakharov-type axion framework in which colored fermions and scalars act as two-loop Majorana neutrino-mass mediators. The global Pec…
XENONnT and LUX-ZEPLIN constraints on DSNB-boosted dark matter
Valentina De Romeri, Anirban Majumdar, Dimitrios K. Papoulias +1
We consider a scenario in which dark matter particles are accelerated to semi-relativistic velocities through their scattering with the Diffuse Supernova Neutrino Background. Such…
Neutrino Mass Sum Rules from Modular Symmetry
Salvador Centelles Chuliá, Ranjeet Kumar, Oleg Popov +1
Modular symmetries offer a dynamic approach to understanding the flavour structure of leptonic mixing. Using the modular flavour symmetry integrated in a type-II se…
Phenomenology of the simplest linear seesaw mechanism
Aditya Batra, Praveen Bharadwaj, Sanjoy Mandal +2
The linear seesaw mechanism provides a simple way to generate neutrino masses. In addition to Standard Model particles, it includes quasi-Dirac leptons as neutrino mass mediators,…
Large lepton number violation at colliders: predictions from the minimal linear seesaw mechanism
Aditya Batra, Praveen Bharadwaj, Sanjoy Mandal +2
Small neutrino masses can be sourced by a tiny vacuum expectation value of a leptophilic Higgs doublet, and mediated by Quasi-Dirac heavy neutrinos. In such simplest linear seesaw…
Can Leptonic Mixing Matrix have a Wolfenstein Form?
Ankur Panchal, G. Rajasekaran, Rahul Srivastava
We analyze the possibility of the leptonic mixing matrix having a Wolfenstein form at the Grand Unified Theory scale. The renormalization group evolution of masses and mixing angle…
model in light of the CDF II result
Sanjoy Mandal, Hemant Prajapati, Rahul Srivastava
Recent CDF II collaboration's result on mass measurements contradict Standard Model prediction, requiring new physics to explain this anomaly. Such new physics may manifest thr…
Decay: Smoking Gun Signature of Wrong-Sign Coupling
Aditya Batra, Sanjoy Mandal, Rahul Srivastava
We perform a model-independent study of new physics effects in the Higgs decay , focusing on scenarios that spoil the accidental cancellation between the direct and indir…
W-mass Anomaly in the Simplest Linear Seesaw Mechanism
Aditya Batra, Praveen Bharadwaj, Sanjoy Mandal +2
The simplest linear seesaw mechanism can accommodate the new CDF-II mass measurement. In addition to Standard Model particles, the model includes quasi-Dirac leptons, and a sec…
Physics implications of recent Dresden-II reactor data
Anirban Majumdar, Dimitrios K. Papoulias, Rahul Srivastava +1
Prompted by the recent Dresden-II reactor data we examine its implications for the determination of the weak mixing angle, paying attention to the effect of the quenching function.…
Implications of first LZ and XENONnT results: A comparative study of neutrino properties and light mediators
ShivaSankar K. A., Anirban Majumdar, Dimitrios K. Papoulias +2
Next generation direct dark matter detection experiments are favorable facilities to probe neutrino properties and light mediators beyond the Standard Model. We explore the implica…
CDF-II W boson mass in the Dirac Scotogenic model
Salvador Centelles Chuliá, Rahul Srivastava, Sushant Yadav
The Dirac scotogenic model provides an elegant mechanism which explains small Dirac neutrino masses and neutrino mixing, with a single symmetry simultaneously protecting the ``Dira…
