Small Cues, Big Consequences: Learning Pivotal Cues for Multimodal Meme Classification
Akshit Sharma, Prashant W. Patil
Memes often derive their harmful, hateful, or sarcastic meaning from small but decisive visual, textual, or cross-modal cues. Existing multimodal classifiers can miss such evidence…
Gamma-Ray Echo as a Probe of Supernova Neutrino Emission Anisotropy and Long-Baseline Effects
Garv Chauhan, Cecilia Lunardini, Yago Porto
During a core-collapse supernova (CCSN), the emitted electron antineutrino () burst initiates inverse beta decay (IBD) in the outer hydrogen layer of the stellar envelope.…
511 keV Gamma Ray Echo from Particle Decays in Supernovae
Garv Chauhan, Cecilia Lunardini
The formation of a hot and dense core in a core-collapse supernova (SN) can produce massive Beyond Standard Model (BSM) particles. These particles can decay in the stellar envelope…
LIQUIDating the Gallium Anomaly
Garv Chauhan, Patrick Huber
The gallium anomaly has a global significance of greater than . Most viable BSM solutions quickly run into strong tensions with reactor and solar neutrino data. We propose to u…
The Dark Matter Diffused Supernova Neutrino Background
Garv Chauhan, R. Andrew Gustafson, Gonzalo Herrera +2
We consider neutrinos scattering off Milky Way dark matter and the impact of this scattering on supernovae neutrinos. This can take the form of attenuation on the initial flux of n…
Supernova Gamma-Ray Constraints from Heavy Sterile Neutrino Decays
Garv Chauhan, R. Andrew Gustafson, Ian M. Shoemaker
Heavy sterile neutrinos can be produced in core-collapse supernovae (CCSNe), which are superb particle generators because of their high densities and temperatures. If the sterile n…
Neutron Stars as a Probe of Cosmic Neutrino Background
Garv Chauhan
The Cosmic Neutrino Background (CB) constitutes the last observable prediction of the standard cosmological model, which has yet to be detected directly. In this work, we show h…
Collider Tests of Flavored Resonant Leptogenesis in the Model
Garv Chauhan
We study the generation of baryon asymmetry through the flavored resonant leptogenesis in the extension of the Standard Model. Being a generalization of the $U(1)_{B\text{…
Impact of the cosmic neutrino background on long-range force searches
Garv Chauhan, Xun-Jie Xu
Light bosons can mediate long-range forces. We show that light bosonic mediators interacting with a background medium, in particular, with the cosmic neutrino background (CB), m…
Probing the Sterile Neutrino Dipole Portal with SN1987A and Low-Energy Supernovae
Garv Chauhan, Shunsaku Horiuchi, Patrick Huber +1
BSM electromagnetic properties of neutrinos may lead to copious production of sterile neutrinos in the hot and dense core of a core-collapse supernova. In this work, we focus on th…
Phenomenology of Lepton Masses and Mixing with Discrete Flavor Symmetries
Garv Chauhan, P. S. Bhupal Dev, Ievgen Dubovyk +6
The observed pattern of fermion masses and mixing is an outstanding puzzle in particle physics, generally known as the flavor problem. Over the years, guided by precision neutrino…
Low-Energy Supernovae Bounds on Sterile Neutrinos
Garv Chauhan, Shunsaku Horiuchi, Patrick Huber +1
Sterile neutrinos can be produced through mixing with active neutrinos in the hot, dense core of a core-collapse supernova (SN). The standard bounds on the active-sterile mixing ($…
Gravity-improved metastability bounds for the Type-I Seesaw Mechanism
Garv Chauhan, Thomas Steingasser
Right-handed neutrinos (RHN) destabilize the electroweak vacuum by increasing its decay rate. In the SM, the latter is dominated by physics at the RG scale at which reaches its…

Garv Chauhan, P. S. Bhupal Dev, Xun-Jie Xu
We consider a hidden gauge symmetry under which only the right-handed neutrinos () are charged. The corresponding gauge boson is referred to as the -philic $Z'…
Discrete Flavor Symmetries and Lepton Masses and Mixings
Garv Chauhan, P. S. Bhupal Dev, Bartosz Dziewit +6
We discuss neutrino mass and mixing models based on discrete flavor symmetries. These models can include a variety of new interactions and non-standard particles such as sterile ne…
The Forward Physics Facility at the High-Luminosity LHC
Jonathan L. Feng, Felix Kling, Mary Hall Reno +233
High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing L…
Interplay between Resonant Leptogenesis, Neutrinoless Double Beta Decay and Collider Signals in a Model with Flavor and CP Symmetries
Garv Chauhan, P. S. Bhupal Dev
We present a low-scale type-I seesaw scenario with discrete flavor and CP symmetries. This scenario not only explains the measured values of the lepton mixing angles, but also make…
How dark is the -philic dark photon?
Garv Chauhan, Xun-Jie Xu
We consider a generic dark photon that arises from a hidden gauge symmetry imposed on right-handed neutrinos (). Such a -philic dark photon is naturally dark d…
Neutrino Non-Standard Interactions via Light Scalars in the Earth, Sun, Supernovae and the Early Universe
K. S. Babu, Garv Chauhan, P. S. Bhupal Dev
Non-standard interactions (NSI) of neutrinos with matter mediated by a scalar field would induce medium-dependent neutrino masses which can modify oscillation probabilities. Genera…
Vacuum Stability and Symmetry Breaking in Left-Right Symmetric Model
Garv Chauhan
We derive analytic necessary and sufficient conditions for the vacuum stability of the left-right symmetric model by using the concepts of copositivity and gauge orbit spaces. We a…
