Hadronic Paschen-Back effect in charmonium

Iwasaki, Sachio; Oka, Makoto; Suzuki, Kei*; Yoshida, Tetsuya*

AIP Conference Proceedings 2130, p.050001_1 - 050001_8, 2019/07

 Times Cited Count:0 Percentile:0.1

We find a novel phenomenon induced by the interplay between a strong magnetic field and finite orbital angular momenta in hadronic systems, which is analogous to the Paschen-Back effect observed in the field of atomic physics. This effect allows the wave functions to drastically deform. We discuss anisotropic decay from the deformation as a possibility to measure the strength of the magnetic field in heavy-ion collision at LHC, RHIC and SPS, which has not experimentally been measured. As an example we investigate charmonia with finite orbital angular momentum in a strong magnetic field. We calculate the mass spectra and mixing rate. To obtain anisotropic wave functions, we apply the cylindrical Gaussian expansion method, where the Gaussian bases to expand the wave functions have different widths along transverse and longitudinal directions in the cylindrical coordinate.

Mesons with charm and strangeness in nuclear matter

Gubler, P.

AIP Conference Proceedings 2130, p.040015_1 - 040015_8, 2019/07

 Times Cited Count:0 Percentile:0.1

In this talk, results about the behavior of mesons containing strange and charm quarks in nuclear matter will be presented and an outlook will be made on future theoretical and experimental developments related to this topic. Our findings are relevant for future experiments (such as E16) to be carried out at the J-PARC facility.
