QCD-Collapsed Domain Walls: QCD Phase Transition and Gravitational Wave Spectroscopy
Yang Bai, Ting-Kuo Chen, Mrunal Korwar
For a discrete symmetry that is anomalous under QCD, the domain walls produced in the early universe from its spontaneous breaking can naturally annihilate due to QCD instanton eff…
Variant Nelson-Barr Mechanism with Minimal Flavor Violation
Yang Bai, George N. Wojcik
Within the general framework of using spontaneous CP violation to solve the strong CP problem, we construct a variant Nelson-Barr model in which the Standard Model (SM) quark contr…
Origin of nontopological soliton dark matter: solitosynthesis or phase transition
Yang Bai, Sida Lu, Nicholas Orlofsky
This work demonstrates that nontopological solitons with large global charges and masses, even above the Planck scale, can form in the early universe and dominate the dark matter a…
IceCube at the Frontier of Macroscopic Dark Matter Direct Detection
Yang Bai, Joshua Berger, Mrunal Korwar
For a class of macroscopic dark matter models, inelastic scattering of dark matter off a nucleus can generate electromagnetic signatures with GeV-scale energy. The IceCube detector…
Snowmass2021 Cosmic Frontier White Paper: Ultraheavy particle dark matter
Daniel Carney, Nirmal Raj, Yang Bai +25
We outline the unique opportunities and challenges in the search for "ultraheavy" dark matter candidates with masses between roughly and the Planck scale $m_{\rm pl}…
Q-Monopole-Ball: A Topological and Nontopological Soliton
Yang Bai, Sida Lu, Nicholas Orlofsky
Magnetic monopoles and Q-balls are examples of topological and nontopological solitons, respectively. A new soliton state with both topological and nontopological charges is shown…
Cosmological Constraints on First-Order Phase Transitions
Yang Bai, Mrunal Korwar
First-order phase transitions exist in many models beyond the Standard Model and can generate detectable stochastic gravitational waves for a strong one. Using the cosmological obs…
Catalyzed Baryogenesis
Yang Bai, Joshua Berger, Mrunal Korwar +1
A novel mechanism, "catalyzed baryogenesis," is proposed to explain the observed baryon asymmetry in our universe. In this mechanism, the motion of a ball-like catalyst provides th…
Muon g-2 from Millicharged Hidden Confining Sector
Yang Bai, Seung J. Lee, Minho Son +1
We provide a novel explanation to the muon excess with new physics contributions at the two-loop level. In this scenario, light millicharged particles are introduced to modif…
Muon g-2 in Lepton Portal Dark Matter
Yang Bai, Joshua Berger
The Lepton Portal Dark Matter model, in which dark matter states only coupling to the charged leptons, can explain the excess of the muon anomalous magnetic moment measured by the…
Searching for Magnetic Monopoles with the Earth's Magnetic Field
Yang Bai, Sida Lu, Nicholas Orlofsky
Magnetic monopoles have long been predicted in theory and could exist as a stable object in our universe. As they move around in galaxies, magnetic monopoles could be captured by a…
Global Electroweak Symmetric Vacuum
Yang Bai, Seung J. Lee, Minho Son +1
Although the Higgs potential in the Standard Model (SM) contains only a simple electroweak symmetry breaking vacuum in the small field region, additional metastable or global vacua…
Hairy Magnetic and Dyonic Black Holes in the Standard Model
Yang Bai, Mrunal Korwar
Spherically symmetric magnetic and dyonic black holes with a magnetic charge are studied in the Standard Model and general relativity. A magnetically charged black hole with…
Dynamical Inflection Point Inflation
Yang Bai, Daniel Stolarski
We provide a mechanism to obtain multiple inflection points for the inflaton potential based on the Coleman-Weinberg potential. The key ingredient is the existence of zeros of the…
Phenomenology of Magnetic Black Holes with Electroweak-Symmetric Coronas
Yang Bai, Joshua Berger, Mrunal Korwar +1
Magnetically charged black holes (MBHs) are interesting solutions of the Standard Model and general relativity. They may possess a "hairy" electroweak-symmetric corona outside the…
Electroweak-Symmetric Dark Monopoles from Preheating
Yang Bai, Mrunal Korwar, Nicholas Orlofsky
If the dark sector contains 't Hooft-Polyakov monopoles and a small enough dark gauge coupling, dark monopoles could be a macroscopic dark matter candidate. Its Higgs-portal coupli…
Reinterpretation of LHC Results for New Physics: Status and Recommendations after Run 2
Waleed Abdallah, Shehu AbdusSalam, Azar Ahmadov +139
We report on the status of efforts to improve the reinterpretation of searches and measurements at the LHC in terms of models for new physics, in the context of the LHC Reinterpret…
Nucleus Capture by Macroscopic Dark Matter
Yang Bai, Joshua Berger
For a class of macroscopic dark matter with a large interaction strength with Standard Model particles, a nucleus could be captured by the dense, heavy dark matter as it traverses…
Electroweak Symmetric Dark Matter Balls
Eduardo Pontón, Yang Bai, Bithika Jain
In the simple Higgs-portal dark matter model with a conserved dark matter number, we show that there exists a non-topological soliton state of dark matter. This state has smaller e…
Primordial Extremal Black Holes as Dark Matter
Yang Bai, Nicholas Orlofsky
We show that primordial (nearly) extremal black holes with a wide range of masses from the Planck scale to around g could be cosmologically stable and explain dark matter, g…
Dark Quark Nuggets
Yang Bai, Andrew J. Long, Sida Lu
"Dark quark nuggets", a lump of dark quark matter, can be produced in the early universe for a wide range of confining gauge theories and serve as a macroscopic dark matter candida…
Hexapod Coloron at the LHC
Yang Bai, Sida Lu, Qian-Fei Xiang
Instead of the usual dijet decay, the coloron may mainly decay into its own "Higgs bosons", which subsequently decay into many jets. This is a general feature of the renormalizable…
Six Flavor Quark Matter
Yang Bai, Andrew J. Long
Macroscopic nuggets of quark matter were proposed several decades ago as a candidate for dark matter. The formation of these objects in the early universe requires the QCD phase tr…
Collider Tests of the Renormalizable Coloron Model
Yang Bai, Bogdan A. Dobrescu
The coloron, a massive version of the gluon present in gauge extensions of QCD, has been searched for at the LHC as a dijet or top quark pair resonance. We point out that in the Re…
