Primer on Axion Physics
Felix Yu
I review the canonical axion potential, with an emphasis on the field theory underlying radial and angular modes of complex scalar fields. I present the explicit calculation of the…
What can a GNOME do? Search targets for the Global Network of Optical Magnetometers for Exotic physics searches
S. Afach, D. Aybas Tumturk, H. Bekker +50
Numerous observations suggest that there exist undiscovered beyond-the-Standard-Model particles and fields. Because of their unknown nature, these exotic particles and fields could…
A Lighter QCD Axion from Anarchy
Fatemeh Elahi, Gilly Elor, Alexey Kivel +3
We introduce the Anarchic Axion, a class of axion models which solves the Strong CP problem within current nEDM constraints with a lighter than usual QCD axion, thus populating new…
Axion Couplings in Gauged Extensions of the Standard Model
Alexey Kivel, Julien Laux, Felix Yu
We explore the effective theory of an axion in a gauged baryon number symmetry extension of the Standard Model (SM), where the axion is realized from a Dine-Fischler-Srednicki-Zhit…
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…
Supersizing axions with small size instantons
Alexey Kivel, Julien Laux, Felix Yu
We construct a new framework to calculate the enhancement of axion masses and concomitant effects on axion-meson mixing arising from small size instantons (SSIs), which originate i…
Displaying dark matter constraints from colliders with varying simplified model parameters
Andreas Albert, Antonio Boveia, Oleg Brandt +17
The search for dark matter is one of the main science drivers of the particle and astroparticle physics communities. Determining the nature of dark matter will require a broad appr…
Dijet and electroweak limits on a boson coupled to quarks
Bogdan A. Dobrescu, Felix Yu
An insightful way of presenting the LHC limits on dijet resonances is the coupling-mass plot for a boson that has flavor-independent quark interactions. This also illustrates…
Probing new gauge symmetries via exotic decays
Lisa Michaels, Felix Yu
New gauge theories involving Standard Model (SM) fermions typically require additional electroweak fermions for anomaly cancellation. We study the non-decoupling properties…
Collider constraints and new tests of color octet vectors
Malte Buschmann, Felix Yu
We analyze the collider sensitivity for new colored resonances in , , and final states. While searches in the single production channel are model-dependen…
A Tale of Two Portals: Testing Light, Hidden New Physics at Future Colliders
Jia Liu, Xiao-Ping Wang, Felix Yu
We investigate the prospects for producing new, light, hidden states at a future collider in a Higgsed dark model, which we call the Double Dark Portal model. Th…
Exotic Signals of Vectorlike Quarks
Bogdan A. Dobrescu, Felix Yu
Vectorlike fermions are an important target for hadron collider searches. We show that the vectorlike quarks may predominantly decay via higher-dimensional operators into a quark p…
Phenomenology of Enhanced Light Quark Yukawa Couplings and the Charge Asymmetry
Felix Yu
I propose the measurement of the charge asymmetry as a consistency test for the Standard Model (SM) Higgs, which is sensitive to enhanced Yukawa couplings of the first an…
Hunting for Dark Matter Coannihilation by Mixing Dijet Resonances and Missing Transverse Energy
Malte Buschmann, Sonia El Hedri, Anna Kaminska +5
Simplified models of the dark matter (co)annihilation mechanism predict striking new collider signatures untested by current searches. These models, which were codified in the coan…
Angular observables for spin discrimination in boosted diboson final states
Malte Buschmann, Felix Yu
We investigate the prospects for spin determination of a heavy diboson resonance using angular observables. Focusing in particular on boosted fully hadronic final states, we detail…
The Coannihilation Codex
Michael J. Baker, Joachim Brod, Sonia El Hedri +8
We present a general classification of simplified models that lead to dark matter (DM) coannihilation processes of the form DM + X SM + SM, where X is a coann…
Supersymmetric Sub-Electroweak Scale Dark Matter, the Galactic Center Gamma-ray Excess, and Exotic Decays of the 125 GeV Higgs Boson
Jinrui Huang, Tao Liu, Lian-Tao Wang +1
We continue our exploration of the nearly Peccei-Quinn symmetric limit shared by common singlet extensions of the Minimal Supersymmetric Standard Model. This limit has been establi…
Anatomizing Exotic Production of the Higgs Boson
Felix Yu
We discuss exotic production modes of the Higgs boson and how their phenomenology can be probed in current Higgs analyses. We highlight the importance of differential distributions…
Constraining RS Models by Future Flavor and Collider Measurements: A Snowmass Whitepaper
Kaustubh Agashe, Martin Bauer, Florian Goertz +4
Randall-Sundrum models are models of quark flavor, because they explain the hierarchies in the quark masses and mixings in terms of order one localization parameters of extra dimen…
Discovery potential of Kaluza-Klein gluons at hadron colliders: A Snowmass whitepaper
Kyoungchul Kong, Felix Yu
We investigate the discovery potential of Kaluza-Klein gluons as a dijet resonance at hadron colliders with different center-of-mass energies, from 14 TeV to 33 TeV to 100 TeV. We…
Measuring CP Violation in at Colliders
Roni Harnik, Adam Martin, Takemichi Okui +2
We investigate the LHC and Higgs Factory prospects for measuring the CP phase in the Higgs-tau-tau coupling. Currently this phase can be anywhere between 0 degrees (CP even) and 90…
Di-jet resonances at future hadron colliders: A Snowmass whitepaper
Felix Yu
I investigate the sensitivity of future hadron colliders to di-jet resonances arising from Z' or coloron models. The projected discovery potential and exclusion limits for these re…
Coupling--mass mapping of di-jet peak searches
Bogdan A. Dobrescu, Felix Yu
