Escaping Solar Capture: Majoron mediated Elastic Dark Matter for the LZ 248~keV Event
Salvador Centelles Chuliá, Ayan Chattaraj, Rahul Srivastava +1
We interpret the nuclear-recoil candidate reported by LZ through elastic dark matter scattering mediated by a light Majoron. The Majoron provides a natural…
Can Elastic Neutrino Scattering Account for the LZ230616 Event?
Ayan Chattaraj, Anirban Majumdar, Dimitrios K. Papoulias +1
Recently, the LUX-ZEPLIN (LZ) Collaboration reported an isolated nuclear-recoil event at , in a region where the expe…
Precision Tests of SM and new physics with the COHERENT Ge-mini and TEXONO data
Tousib Ahmed, Ayan Chattaraj, Anirban Majumdar +2
A comprehensive numerical analysis of the latest germanium based CENS data from the COHERENT Ge-mini and TEXONO experiments has been conducted to test the Standard Model (SM) an…
Primordial black holes as cosmic accelerators of light dark matter: Novel direct detection constraints
Sk Jeesun, Anirban Majumdar, Rahul Srivastava
Current multi-tonne-scale dark matter (DM) detectors are largely incapable of detecting light dark matter from the Galactic halo due to the energy threshold limitations of their re…
New light mediators and the neutrino fog: Implications from XENONnT nuclear recoil data
Valentina De Romeri, Anirban Majumdar, Dimitrios K. Papoulias +1
Current ton-scale, xenon-based dark matter (DM) direct detection experiments have now reached the sensitivity required to observe solar neutrinos, marking the onset of the so-calle…
Probing conventional and new physics at the ESS with coherent elastic neutrino-nucleus scattering
Ayan Chattaraj, Anirban Majumdar, Dimitrios K. Papoulias +1
We explore the potential of the European Spallation Source (ESS) in probing physics within and beyond the Standard Model (SM), based on future measurements of coherent elastic neut…
Probing Standard Model and Beyond with Reactor CENS Data of CONUS+ experiment
Ayan Chattaraj, Anirban Majumdar, Rahul Srivastava
We explore the potential of reactor antineutrino-induced Coherent Elastic Neutrino-Nucleus Scattering (CENS) data from the CONUS+ experiment to investigate both the Standard Mod…
Constraining low scale dark hypercharge symmetry at spallation, reactor and Dark Matter direct detection experiments
Anirban Majumdar, Dimitrios K. Papoulias, Hemant Prajapati +1
Coherent elastic neutrino-nucleus (CENS) and elastic neutrino-electron scattering (EES) data are exploited to constrain ``chiral'' gauged models with light vector…
Dark hyperCharge Symmetry
Hemant Prajapati, Rahul Srivastava
We introduce a new class of symmetries where all Standard Model fermions are ``chiral," i.e., the left- and right-handed components have different charges under the $U(1)_…
