A short theoretical review of charmonium production
An-Ping Chen, Yan-Qing Ma, Hong Zhang
In this paper, we review the current status of the phenomenological study of quarkonium production in high energy collisions. After a brief introduction of several important models…
Axion Stars
Eric Braaten, Hong Zhang
The particle that makes up the dark matter of the universe could be an axion or axion-like particle. A collection of axions can condense into a bound Bose-Einstein condensate calle…
Classical Nonrelativistic Effective Field Theories for a Real Scalar Field
Eric Braaten, Abhishek Mohapatra, Hong Zhang
A classical nonrelativistic effective field theory for a real Lorentz-scalar field is most conveniently formulated in terms of a complex scalar field . There have been two d…
Effective field theory for resonant wino dark matter
Evan Johnson, Hong Zhang, Eric Braaten
Enhancements in WIMP annihilation rates have been identified with a nonperturbative "Sommerfeld enhancement" arising from the exchange of light mediators. At certain critical value…
Zero-Range Effective Field Theory for Resonant Wino Dark Matter I. Framework
Eric Braaten, Evan Johnson, Hong Zhang
The most dramatic "Sommerfeld enhancements" of neutral-wino-pair annihilation occur when the wino mass is near a critical value where there is a zero-energy S-wave resonance at the…
Rotation-invariant observables in polarization measurements
Yan-Qing Ma, Jian-Wei Qiu, Hong Zhang
Polarization measurements provide a detailed method to test the Standard Model and to search for new physics. Most previous studies depend on pre-selected coordinates, which blurs…
