Lepton Flavor Violation: From Muon Decays to Muon Colliders
Pouya Asadi, Hengameh Bagherian, Katherine Fraser +2
We investigate the unique potential of a high-energy muon collider to probe lepton-flavor-violating signals arising from physics beyond the Standard Model (SM). Low-energy, precisi…
The Quality/Cosmology Tension for a Post-Inflation QCD Axion
Qianshu Lu, Matthew Reece, Zhiquan Sun
It is difficult to construct a post-inflation QCD axion model that solves the axion quality problem (and hence the Strong CP problem) without introducing a cosmological disaster. I…
Savior Curvatons and Large non-Gaussianity
Jackie Lodman, Qianshu Lu, Lisa Randall
Curvatons are light (compared to the Hubble scale during inflation) spectator fields during inflation that potentially contribute to adiabatic curvature perturbations post-inflatio…
Towards a Muon Collider
Carlotta Accettura, Dean Adams, Rohit Agarwal +294
A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions a…
Chiral Nelson--Barr Models: Quality and Cosmology
Pouya Asadi, Samuel Homiller, Qianshu Lu +1
It was recently shown that domain walls from the spontaneous breaking of CP symmetry are exactly stable, and must be inflated away to recover a viable cosmology. We investigate the…
Fully-heavy hexaquarks in a constituent quark model
Qi-Fang Lü, Dian-Yong Chen, Yu-Bing Dong
In this work, we systematically investigate the mass spectra of fully-heavy hexaquarks within a constituent quark model by including the color Coulomb potential, linear confining p…
Complementary Signals of Lepton Flavor Violation at a High-Energy Muon Collider
Samuel Homiller, Qianshu Lu, Matthew Reece
A muon collider would be a powerful probe of flavor violation in new physics. There is a strong complementary case for collider measurements and precision low-energy probes of lept…
The physics case of a 3 TeV muon collider stage
Jorge De Blas, Dario Buttazzo, Rodolfo Capdevilla +131
In the path towards a muon collider with center of mass energy of 10 TeV or more, a stage at 3 TeV emerges as an appealing option. Reviewing the physics potential of such muon coll…
Missing Scalars at the Cosmological Collider
Qianshu Lu, Matthew Reece, Zhong-Zhi Xianyu
Light scalar fields typically develop spatially varying backgrounds during inflation. Very often they do not directly affect the density perturbations, but interact with other fiel…
The Muon Smasher's Guide
Hind Al Ali, Nima Arkani-Hamed, Ian Banta +31
We lay out a comprehensive physics case for a future high-energy muon collider, exploring a range of collision energies (from 1 to 100 TeV) and luminosities. We highlight the advan…
Spillway Preheating
JiJi Fan, Kaloian D. Lozanov, Qianshu Lu
In traditional models only an order one fraction of energy is transferred from the inflaton to radiation through nonperturbative resonance production in preheating immediately afte…
Interpreting the Electron EDM Constraint
Cari Cesarotti, Qianshu Lu, Yuichiro Nakai +2
The ACME collaboration has recently announced a new constraint on the electron EDM, , from measurements of the ThO molecule. This is a p…
Higgs Boson Decays to Dark Photons through the Vectorized Lepton Portal
Qianshu Lu, David E. Morrissey, Alexander M. Wijangco
Vector-like fermions charged under both the Standard Model and a new dark gauge group arise in many theories of new physics. If these fermions include an electroweak doublet and si…
