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…
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…
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…
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…
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…
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…
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…
LHC Signals from Cascade Decays of Warped Vector Resonances
Kaustubh S. Agashe, Jack Collins, Peizhi Du +3
Recently (arXiv:1608.00526), a new framework for warped higher-dimensional compactifications with "bulk" standard model (SM) was proposed: in addition to the UV (Planck scale) and…
Interactions of a Stabilized Radion and Duality
Zackaria Chacko, Rashmish K. Mishra, Daniel Stolarski +1
We determine the couplings of the graviscalar radion in Randall-Sundrum models to Standard Model fields propagating in the bulk of the space, taking into account effects arising fr…
Dynamics of a Stabilized Radion and Duality
Zackaria Chacko, Rashmish K. Mishra, Daniel Stolarski
We construct the effective theory of the graviscalar radion in the Randall-Sundrum scenario, taking into account effects arising from the stabilization of the extra dimension throu…
Resonance at 125 GeV: Higgs or Dilaton/Radion?
Zackaria Chacko, Roberto Franceschini, Rashmish K. Mishra
We consider the possibility that the new particle that has been observed at 125 GeV is not the Standard Model (SM) Higgs, but instead the dilaton associated with an approximate con…
Effective Theory of a Light Dilaton
Zackaria Chacko, Rashmish K. Mishra
We consider scenarios where strong conformal dynamics constitutes the ultraviolet completion of the physics that drives electroweak symmetry breaking. We show that in theories wher…
