Flavoured with Dark Lepton Seasoning
Harun Acaroğlu, Prateek Agrawal, Monika Blanke
As a joint explanation for the dark matter (DM) problem and the muon anomaly, we propose a simplified model of lepton-flavoured complex scalar DM with couplings to both the…
Lepton-Flavoured Scalar Dark Matter in Dark Minimal Flavour Violation
Harun Acaroğlu, Prateek Agrawal, Monika Blanke
We study a simplified model of lepton-flavoured complex scalar dark matter set up in the Dark Minimal Flavour Violation framework. In this model the Standard Model is extended by a…
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…
Searching for axion forces with precision precession in storage rings
Prateek Agrawal, David E. Kaplan, On Kim +2
We consider different types of storage rings as precision probes of axion-mediated monopole-dipole forces. We show that current and planned experiments aiming to measure magnetic a…
Axion Couplings in Grand Unified Theories
Prateek Agrawal, Michael Nee, Mario Reig
We show that the couplings of axions to gauge bosons are highly restricted in Grand Unified Theories where the standard model is embedded in a simple 4D gauge group. The topologica…
Some open questions in axion theory
Prateek Agrawal, Kim V. Berghaus, JiJi Fan +3
This white paper collects some open questions in several different aspects of axion theories. The questions are related to quantization of axion couplings, axion-magnetic monopole…
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…
The Boring Monopole
Prateek Agrawal, Michael Nee
We study false vacuum decays catalysed by magnetic monopoles which act as tunnelling sites with exponentially enhanced decay rates. The field profiles describing the decay do not h…
The Swapland
Prateek Agrawal, Hengameh Bagherian, Cari Cesarotti +6
All the news that's (un)fit to publish.
Avoided Deconfinement in Randall-Sundrum Models
Prateek Agrawal, Michael Nee
We study first order phase transitions in Randall-Sundrum models in the early universe dual to confinement in large- gauge theories. The transition rate to the confined phase is…
Feebly-Interacting Particles:FIPs 2020 Workshop Report
Prateek Agrawal, Martin Bauer, James Beacham +43
With the establishment and maturation of the experimental programs searching for new physics with sizeable couplings at the LHC, there is an increasing interest in the broader part…
Topological Gravity as the Early Phase of Our Universe
Prateek Agrawal, Sergei Gukov, Georges Obied +1
Motivated by string dualities we propose topological gravity as the early phase of our universe. The topological nature of this phase naturally leads to the explanation of many of…
Axion string signatures II: A cosmological plasma collider
Prateek Agrawal, Anson Hook, Junwu Huang +1
We study early and late time signatures of both QCD axion strings and hyperlight axion strings (axiverse strings). We focus on charge deposition onto axion strings from electromagn…
Systematizing the Effective Theory of Self-Interacting Dark Matter
Prateek Agrawal, Aditya Parikh, Matthew Reece
If dark matter has strong self-interactions, future astrophysical and cosmological observations, together with a clearer understanding of baryonic feedback effects, might be used t…
A CMB Millikan Experiment with Cosmic Axiverse Strings
Prateek Agrawal, Anson Hook, Junwu Huang
We study axion strings of hyperlight axions coupled to photons. Hyperlight axions -- axions lighter than Hubble at recombination -- are a generic prediction of the string axiverse.…
Tension, Swampland Conjectures and the Epoch of Fading Dark Matter
Prateek Agrawal, Georges Obied, Cumrun Vafa
Motivated by the swampland dS conjecture, we consider a rolling scalar field as the source of dark energy. Furthermore, the swampland distance conjecture suggests that the rolling…
Rock 'n' Roll Solutions to the Hubble Tension
Prateek Agrawal, Francis-Yan Cyr-Racine, David Pinner +1
Local measurements of the Hubble parameter are increasingly in tension with the value inferred from a CDM fit to the cosmic microwave background (CMB) data. In this paper, we co…
Dark Energy and the Refined de Sitter Conjecture
Prateek Agrawal, Georges Obied
We revisit the phenomenology of quintessence models in light of the recently refined version of the de Sitter Swampland conjecture, which includes the possibility of unstable de Si…
Relic Abundance of Dark Photon Dark Matter
Prateek Agrawal, Naoya Kitajima, Matthew Reece +2
We present a new mechanism for producing the correct relic abundance of dark photon dark matter over a wide range of its mass, extending down to . The dark m…
On the Cosmological Implications of the String Swampland
Prateek Agrawal, Georges Obied, Paul J. Steinhardt +1
We study constraints imposed by two proposed string Swampland criteria on cosmology. These criteria involve an upper bound on the range traversed by scalar fields as well as a lowe…
A Flavorful Factoring of the Strong CP Problem
Prateek Agrawal, Kiel Howe
Motivated by the intimate connection between the strong CP problem and the flavor structure of the Standard Model, we present a flavor model that revives and extends the classic ${…
Factoring the Strong CP Problem
Prateek Agrawal, Kiel Howe
We present a new mechanism to solve the strong CP problem using axions, each dynamically relaxing part of the parameter. At high energies the $SU(3)_…
Experimental Targets for Photon Couplings of the QCD Axion
Prateek Agrawal, JiJi Fan, Matthew Reece +1
The QCD axion's coupling to photons is often assumed to lie in a narrow band as a function of the axion mass. We demonstrate that several simple mechanisms, in addition to the phot…
Opening up the QCD axion window
Prateek Agrawal, Gustavo Marques-Tavares, Wei Xue
We present a new mechanism to deplete the energy density of the QCD axion, making decay constants as high as viable for generic initial conditions. I…
