Velocity dependence of the mass modifications of and mesons in 12 GeV reactions

Wataru Nakai, Kazuya Aoki, Junsei Chiba +26

This study measured the invariant mass spectra of and mesons in the decay channel for 12 GeV (12.9 GeV/) and reactions ($\sqrt{s}…

Analysis of spectral modification of mesons at finite density using a transport approach in the 12 GeV pA reactions

PS E325 Collaboration, Masaya Ichikawa, Philipp Gubler +26

The hadron spectrum at finite density is an important observable for exploring the origin of hadron masses. In the KEK-PS E325 experiment, the di-electron decays of phi mesons insi…

Search for Theta+ via K+p -> pi+X reaction with a 1.2 GeV/c K+ beam

K. Miwa, S. Dairaku, D. Nakajima

The Theta+ was searched for via the K+p -> pi+X reaction using the 1.2 GeV/c K+ beam at the K6 beam line of the KEK-PS 12 GeV Proton Synchrotron. In the missing mass spectrum of th…

Nuclear-matter modification of decay widths in the and channels

F. Sakuma, J. Chiba, H. En'yo +23

The invariant mass spectra of are measured in 12 GeV reactions in order to search for the in-medium modification of mesons. The observed sp…

Nuclear mass number dependence of inclusive production of omega and phi mesons in 12 GeV p + A collisions

T. Tabaru, H. En'yo, R. Muto +23

The inclusive production of omega and phi mesons is studied in the backward region of the interaction of 12 GeV protons with polyethylene, carbon, and copper targets. The mesons ar…
