Temperature Dependence of the Axion Mass in a Scenario Where the Restoration of Chiral Symmetry Drives the Restoration of the UA(1) Symmetry

open access: yesUniverse, 2019
The temperature (T) dependence of the axion mass is predicted for T ′ s up to ∼ 2.3 × the chiral restoration temperature of QCD. The axion is related to the U A ( 1 ) anomaly. The squared axion mass m a

QCD equations of state and speed of sound in neutron stars

open access: yesAAPPS Bulletin, 2021
Neutron stars are cosmic laboratories to study dense matter in quantum chromodynamics (QCD). The observable mass-radius relations of neutron stars are determined by QCD equations of state and can reflect the properties of QCD phase transitions.

Measurement of Light-Cone Wave Functions by Diffractive Dissociation

open access: yes, 2002
Diffractive dissociation of particles can be used to study their light-cone wave functions. Results from Fermilab experiment E791 for diffractive dissociation of 500 GeV/c pi- mesons into di-jets show that the |q qbar> light-cone asymptotic wave function

The Lattice QCD Study of the Three-Nucleon Force

open access: yes, 2011
We investigate three-nucleon forces (3NF) from lattice QCD simulations, utilizing the Nambu-Bethe-Salpeter (NBS) wave function to determine two-nucleon forces (2NF) and 3NF on the same footing.

Instantons and the Large N_c Limit of QCD [PDF]

open access: yes, 2002
We summarize our current understanding of instantons in the large N_c limit of QCD. We also present some recent results from simulations of the instanton liquid in QCD for N_c>3.Comment: 10 pages; talk given at the Workshop on the Phenomenology of Large
