Emergent chirality and superfluidity of parity-doubled baryons in neutron stars
Shigehiro Yasui, Muneto Nitta, Chihiro Sasaki
We propose novel superfluids induced by the parity-doubled baryons. The parity-doubled baryons, i.e., a nucleon with spin-parity and an excited nucleon $N^…
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…
Glueballonia as Hopfions
Yuki Amari, Muneto Nitta, Chihiro Sasaki +3
We work out the Hopfion description of glueballs by inclusively comparing the energy spectra obtained by quantizing Hopfions with experimental data and lattice QCD. Identifying a H…
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…
