Understanding the Quantized Angular Momentum of Rotating Q-balls
Benjamin DeVries, Fabrizio Vassallo, Christopher B. Verhaaren
Non-topological solitons, such as Q-balls, may contribute to the cosmological dark matter. The formation and evolution of Q-balls in the early universe requires an understanding of…
Extended Color Twin Higgs
Brian Batell, Thomas Cochran, Logan Page +1
We describe a novel variation of the mirror Twin Higgs model in which the color gauge group in both sectors is extended to SU(4 and spontaneously broken to SU(3 exclusive…
Geometrizing the Anomaly
Joshua Newey, John Terning, Christopher B. Verhaaren
Recently a manifestly gauge invariant formalism for calculating amplitudes in quantum electrodynamics was outlined in which the field strength, rather than the gauge potential, is…
Visible Collider Signals of Natural Quirks
Joshua Forsyth, Matthew Low, Carson Tenney +1
Though some LHC searches for new physics exceed the TeV scale, there may be discoveries waiting to be made at much lower masses. We outline a simple quirk model, motivated by model…
Schwinger vs Coleman: Magnetic Charge Renormalization
Joshua Newey, John Terning, Christopher B. Verhaaren
The kinetic mixing of two U(1) gauge theories can result in a massless photon that has perturbative couplings to both electric and magnetic charges. This framework can be used to p…
On Q-balls in Anti de Sitter Space
Arvind Rajaraman, Alexander Stewart, Christopher B. Verhaaren
We perform a general analysis of thin-wall Q-balls in AdS space. We provide numeric solutions and highly accurate analytic approximations over much of the parameter space. These an…
Slowly rotating Q-balls
Yahya Almumin, Julian Heeck, Arvind Rajaraman +1
Q-balls are non-topological solitons arising in scalar field theories. Solutions for rotating Q-balls (and the related boson stars) have been shown to exist when the angular moment…
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…
Theory, phenomenology, and experimental avenues for dark showers: a Snowmass 2021 report
Guillaume Albouy, Jared Barron, Hugues Beauchesne +51
In this work, we consider the case of a strongly coupled dark/hidden sector, which extends the Standard Model (SM) by adding an additional non-Abelian gauge group. These extensions…
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…
Review of Neutral Naturalness
Brian Batell, Matthew Low, Ethan T. Neil +1
The hierarchy between the mass parameter of the Higgs boson and larger mass scales becomes ever more puzzling as experiments explore higher energies. Neutral naturalness is the umb…
Searches for Long-Lived Particles at the Future FCC-ee
J. Alimena, P. Azzi, M. Bauer +15
The electron-positron stage of the Future Circular Collider, FCC-ee, is a frontier factory for Higgs, top, electroweak, and flavour physics. It is designed to operate in a 100 km c…
Simulating Glueball Production in QCD
David Curtin, Caleb Gemmell, Christopher B. Verhaaren
In an gauge theory with zero light quark flavours , the only hadronic states that form below the confinement scale are composite gluon states called glueballs. T…
Excited Q-Balls
Yahya Almumin, Julian Heeck, Arvind Rajaraman +1
Complex scalars in U(1)-symmetric potentials can form stable Q-balls, non-topological solitons that correspond to spherical bound-state solutions. If the U(1) charge of the Q-ball…
Twin Quark Dark Matter From Cogenesis
Can Kilic, Christopher B. Verhaaren, Taewook Youn
We extend the fraternal twin Higgs scenario to include a novel dark matter candidate as well as a mechanism for generating a matter/antimatter asymmetry in both sectors. A spontane…
Proca Q-balls and Q-shells
Julian Heeck, Arvind Rajaraman, Rebecca Riley +1
Non-topological solitons such as Q-balls and Q-shells have been studied for scalar fields invariant under global and gauged U(1) symmetries. We generalize this framework to include…
The Ubiquity of Gauged Q-Shells
Julian Heeck, Arvind Rajaraman, Christopher B. Verhaaren
Non-topological gauged soliton solutions called Q-balls arise in many scalar field theories that are invariant under a U(1) gauge symmetry. The related, but qualitatively distinct,…
Mapping Gauged Q-Balls
Julian Heeck, Arvind Rajaraman, Rebecca Riley +1
Scalar field theories with particular U(1)-symmetric potentials contain non-topological soliton solutions called Q-balls. Promoting the U(1) to a gauge symmetry leads to the more c…
Spurious Poles in the Scattering of Electric and Magnetic Charges
John Terning, Christopher B. Verhaaren
Theories with both electric and magnetic charges ("mutually non-local" theories) have several major obstacles to calculating scattering amplitudes. Even when the interaction arises…
Understanding Q-Balls Beyond the Thin-Wall Limit
Julian Heeck, Arvind Rajaraman, Rebecca Riley +1
Complex scalar fields charged under a global U(1) symmetry can admit non-topological soliton configurations called Q-balls which are stable against decay into individual particles…
Dynamical Evidence For a Fifth Force Explanation of the ATOMKI Nuclear Anomalies
Jonathan L. Feng, Tim M. P. Tait, Christopher B. Verhaaren
Recent anomalies in Be and He nuclear decays can be explained by postulating a fifth force mediated by a new boson . The distributions of both transitions are consistent…
Breaking Mirror Twin Color
Brian Batell, Wei Hu, Christopher B. Verhaaren
We investigate simple extensions of the Mirror Twin Higgs model in which the twin color gauge symmetry and the discrete mirror symmetry are spontaneously broken. This is acco…
A Minimal Model for Neutral Naturalness and pseudo-Nambu-Goldstone Dark Matter
Aqeel Ahmed, Saereh Najjari, Christopher B. Verhaaren
We outline a scenario where both the Higgs and a complex scalar dark matter candidate arise as the pseudo-Nambu-Goldstone bosons of breaking a global symmetry to . T…
