EFT Approaches to Sommerfeld Enhancement and Bound States in Singular Potentials
Arindam Bhattacharya, Rashmish K. Mishra, Tracy R. Slatyer
The Sommerfeld enhancement (SE) from long-range interactions, and the related bound state formation rate, can be important non-perturbative inputs to dark matter (DM) annihilation…
Confinement in Holographic Theories at Finite Theta
Rashmish K. Mishra
A strongly coupled confining gauge theory with a non-zero vacuum angle undergoing a deconfinement to confinement phase transition is studied in the holographic gravitational descri…
Inflation with a Growing Fifth Dimension
Rashmish K. Mishra, Michael Nee, Lisa Randall
Inflation generally assumes a field with nonzero potential that leads to inflationary expansion happening at arbitrarily early times. We demonstrate potentially observable conseque…
Evaporating Axion Dark Matter and the Hubble Constant
Daniel Aloni, Hengameh Bagherian, Rashmish K. Mishra
Axion-like particles are a well-motivated dark matter candidate that can form a condensate with low momentum and high occupation number. In the presence of dark radiation, this con…
Density of States, Black Holes and the Emergent String Conjecture
Alek Bedroya, Rashmish K. Mishra, Max Wiesner
We study universal features of the density of one-particle states in weakly coupled theories of gravity at energies above the quantum gravity cutoff , defined as the scal…
Phase Transition to RS: Cool, not Supercool
Rashmish K. Mishra, Lisa Randall
Motivated by the warped conifold compactification, we model the infrared (IR) dynamics of confining gauge theories in a Randall-Sundrum (RS)-like setup by modifying the stabilizing…
Consequences of a Stabilizing Field's Self-Interactions for RS Cosmology
Rashmish K. Mishra, Lisa Randall
It has been argued that the Randall-Sundrum (RS) phase transition rate is suppressed when the holographic theory corresponds to a large Yang-Mills and when the stabilizing fiel…
Model Agnostic Probes of Dark Sectors at Neutrino Experiments
Marco Costa, Rashmish K. Mishra, Sonali Verma
Present and upcoming neutrino experiments can have considerable sensitivity to dark sectors that interact feebly with the Standard Model. We consider dark sectors interacting with…
Report of the Topical Group on Physics Beyond the Standard Model at Energy Frontier for Snowmass 2021
Tulika Bose, Antonio Boveia, Caterina Doglioni +318
This is the Snowmass2021 Energy Frontier (EF) Beyond the Standard Model (BSM) report. It combines the EF topical group reports of EF08 (Model-specific explorations), EF09 (More gen…
TF08 Snowmass Report: BSM Model Building
Patrick J. Fox, Graham D. Kribs, Hitoshi Murayama +53
We summarize the state of Beyond the Standard Model (BSM) model building in particle physics for Snowmass 2021, focusing mainly on several whitepaper contributions to BSM model bui…
Confinement in de Sitter Space and the Swampland
Rashmish K. Mishra
The relation between confinement scale of a gauge theory and the Hubble scale of the background quasi de Sitter space, required to satisfy the Festina Lente criteria ($Λ_…
Snowmass2021 White Paper: Collider Physics Opportunities of Extended Warped Extra-Dimensional Models
Kaustubh Agashe, Jack H. Collins, Peizhi Du +5
While the warped extra-dimensional models provide an attractive solution to both the gauge and the flavor hierarchy problems, the mass scale of new particles predicted by the minim…
Warped Compactifications in Particle Physics, Cosmology and Quantum Gravity
Prateek Agrawal, Cari Cesarotti, Andreas Karch +3
Particle physics has evolved in the past decade through evaluating the consequences of experimental measurements as well as exploiting theoretical tools that permit exploration of…
Probing New Gauge Forces with a High-Energy Muon Beam Dump
Cari Cesarotti, Samuel Homiller, Rashmish K. Mishra +1
We propose a new beam dump experiment at a future TeV-scale muon collider. A beam dump would be an economical and effective way to increase the discovery potential of the collider…
Challenges for Unsupervised Anomaly Detection in Particle Physics
Katherine Fraser, Samuel Homiller, Rashmish K. Mishra +2
Anomaly detection relies on designing a score to determine whether a particular event is uncharacteristic of a given background distribution. One way to define a score is to use au…
Holographic BCFTs and Communicating Black Holes
Hao Geng, Severin Lüst, Rashmish K. Mishra +1
We study the AdS/BCFT duality between two-dimensional conformal field theories with two boundaries and three-dimensional anti-de Sitter space with two Karch-Randall branes. We comp…
Searching for Elusive Dark Sectors with Terrestrial and Celestial Observations
Roberto Contino, Kevin Max, Rashmish K. Mishra
We consider the possible existence of a SM-neutral and light dark sector coupled to the visible sector through irrelevant portal interactions. Scenarios of this kind are motivated…
Mass Agnostic Jet Taggers
Layne Bradshaw, Rashmish K. Mishra, Andrea Mitridate +1
Searching for new physics in large data sets needs a balance between two competing effects---signal identification vs background distortion. In this work, we perform a systematic s…
Detecting a Boosted Diboson Resonance
Kaustubh Agashe, Jack H. Collins, Peizhi Du +3
New light scalar particles in the mass range of hundreds of GeV, decaying into a pair of bosons can appear in several extensions of the SM. The focus of collider studies for…
AdS Asymptotic Symmetries from CFT Mirrors
Rashmish K. Mishra, Arif Mohd, Raman Sundrum
We study Kac-Moody asymptotic symmetries and memory effects in gauge theory and (when accompanied by 4D gravity) in its holographic CFT dual. W…
Dedicated Strategies for Triboson Signals from Cascade Decays of Vector Resonances
Kaustubh Agashe, Jack H. Collins, Peizhi Du +3
New colorless electroweak (EW) charged spin-1 particles with mass of a few TeV arise in numerous extensions of the Standard Model (SM). Decays of such a vector into a pair of SM pa…
A generic anti-QCD jet tagger
J. A. Aguilar-Saavedra, Jack H. Collins, Rashmish K. Mishra
New particles beyond the Standard Model might be produced with a very high boost, for instance if they result from the decay of a heavier particle. If the former decay hadronically…
Asymptotic Symmetries, Holography and Topological Hair
Rashmish K. Mishra, Raman Sundrum
Asymptotic symmetries of AdS quantum gravity and gauge theory are derived by coupling the dual CFT to Chern-Simons gauge theory and 3D gravity in a "probe" large-level limi…
