Proton Spin Decomposition via QCD Sum Rules
HyungJoo Kim, Philipp Gubler, Chihiro Sasaki
We present a novel approach for investigating the spin structure of hadrons based on the two-point function in quantum field theory. In a rotating frame, we derive two independent…

Toward a Direct Measurement of Partial Restoration of Chiral Symmetry at J-PARC E16 via Density-induced Chiral Mixing
Ren Ejima, Philipp Gubler, Chihiro Sasaki +1
The degeneracy of chiral partners is an ideal signal for measuring the restoration of the spontaneously broken chiral symmetry in QCD. In this work, we investigate the observabilit…
