A cosmological case study of a tower of warm dark matter states: naturalness
Saurabh Bansal, Subhajit Ghosh, Matthew Low +1
In this work, we study the cosmological effects of a tower of warm dark matter states on the cosmic microwave background (CMB) and on large-scale structure (LSS). For concreteness,…
Precision Cosmological Constraints on Atomic Dark Matter
Saurabh Bansal, Jared Barron, David Curtin +1
Atomic dark matter is a simple but highly theoretically motivated possibility for an interacting dark sector that could constitute some or all of dark matter. We perform a comprehe…
Enhanced neutrino polarizability
Saurabh Bansal, Gil Paz, Alexey Petrov +2
We point out that neutrinos can have enhanced couplings to photons, if light (pseudo)scalar mediators are present, resulting in potentially measurable neutrino polarizability. We s…
Early-Universe Model Building
Pouya Asadi, Saurabh Bansal, Asher Berlin +37
Theoretical investigations into the evolution of the early universe are an essential part of particle physics that allow us to identify viable extensions to the Standard Model as w…
New Physics Searches at Kaon and Hyperon Factories
Evgueni Goudzovski, Diego Redigolo, Kohsaku Tobioka +61
Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths…
Mirror Twin Higgs Cosmology: Constraints and a Possible Resolution to the and Tensions
Saurabh Bansal, Jeong Han Kim, Christopher Kolda +2
The mirror twin Higgs model (MTH) is a solution to the Higgs hierarchy problem that provides well-predicted cosmological signatures with only three extra parameters: the temperatur…
EinsteinPy: A Community Python Package for General Relativity
Shreyas Bapat, Ritwik Saha, Bhavya Bhatt +46
This paper presents EinsteinPy (version 0.3), a community-developed Python package for gravitational and relativistic astrophysics. Python is a free, easy to use a high-level progr…
Constraining R-parity-violating couplings in -processes at the LHC and in electroweak precision measurements
Saurabh Bansal, Antonio Delgado, Christopher Kolda +1
We find new limits on the R-parity violating (RPV) couplings of the minimal supersymmetric standard model, using Drell-Yan differential cross sections at the LHC and ele…
Limits on R-parity-violating couplings from Drell-Yan processes at the LHC
Saurabh Bansal, Antonio Delgado, Christopher Kolda +1
We find constraints on R-Parity Violating (RPV) couplings of the minimal supersymmetric standard model, using Drell-Yan differential cross sections at the LHC. Specifically, we loo…
On the Minimal Flavor Violating Leptoquark Explanation of the Anomaly
Saurabh Bansal, Rodolfo M. Capdevilla, Christopher Kolda
There has been persistent disagreement between the Standard Model (SM) prediction and experimental measurements of $R_{D^{(*)}}=\mathcal{B}(\bar B \rightarrow D^{(*)} τ\barν_τ)/\ma…
Hunting leptoquarks in monolepton searches
Saurabh Bansal, Rodolfo M. Capdevilla, Antonio Delgado +3
We show that stringent limits on leptoquarks that couple to first-generation quarks and left-handed electrons or muons can be derived from the spectral shape of the charged-current…
