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…
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…
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…
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…
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…
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…
Light Hidden Mesons through the Z Portal
Hsin-Chia Cheng, Lingfeng Li, Ennio Salvioni +1
Confining hidden sectors are an attractive possibility for physics beyond the Standard Model (SM). They are especially motivated by neutral naturalness theories, which reconcile th…
Detecting Dark Matter with Aharonov-Bohm
John Terning, Christopher B. Verhaaren
While the evidence for dark matter continues to grow, the nature of the dark matter remains a mystery. A dark gauge theory can have a small kinetic mixing with the visible…

Zackaria Chacko, Can Kilic, Saereh Najjari +1
We consider the collider signals arising from kinetic mixing between the hypercharge gauge boson of the Standard Model and its twin counterpart in the Mirror Twin Higgs model, in t…
Breaking Mirror Twin Hypercharge
Brian Batell, Christopher B. Verhaaren
The Twin Higgs scenario stabilizes the Higgs mass through an approximate global symmetry and has remained natural in the face of increasingly stringent LHC bounds on colored top pa…
Composite Twin Dark Matter
John Terning, Christopher B. Verhaaren, Kyle Zora
We consider Fraternal Twin Higgs models where the twin bottom quark, , is much heavier than the twin confinement scale. In this limit aspects of quark bound states, like the ma…
Discovering the Twin Higgs Boson with Displaced Decays
Can Kilic, Saereh Najjari, Christopher B. Verhaaren
The Twin Higgs mechanism keeps the scalar sector of the Standard Model (SM) natural while remaining consistent with the non-observation of new colored particles at the Large Hadron…

The Compact Linear Collider (CLIC) is a mature option for the future of high energy physics. It combines the benefits of the clean environment of colliders with operation…
Singleton Portals to the Twin Sector
Fady Bishara, Christopher B. Verhaaren
The mirror twin Higgs framework allows for a natural Higgs mass while being consistent with collider bounds on colored symmetry partners to standard model quarks. This mechanism re…
