New nonet scalar mesons and glueballs: the mass spectra and the production yields in relativistic heavy ion collisions

Shigehiro Yasui, Su Houng Lee, Pok Man Lo +1

We propose a new nonet scheme for scalar mesons consisting of $f_{0} (980)$ , $a_{0} (980)$ , $K_{0}^{*} (1430)$ , and $f_{0} (1770)$ , regarding them as quark-antiquark $P$ -wave states…

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 $N (940)$ with spin-parity $J^{P} = 1/ 2^{+}$ and an excited nucleon $N^…

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…

Strongly interacting matter in extreme magnetic fields

Prabal Adhikari, Martin Ammon, Sidney S. Avancini +58

Magnetic fields are ubiquitous across different physical systems of current interest; from the early Universe, compact astrophysical objects and heavy-ion collisions to condensed m…
