First $π K$ atom lifetime and $π K$ scattering length measurements

B. Adeva, L. Afanasyev, Y. Allkofer +65

The results of a search for hydrogen-like atoms consisting of $π^{\mp} K^{\pm}$ mesons are presented. Evidence for $π K$ atom production by 24 GeV/c protons from CERN PS interacting…

Nuclear-matter modification of decay widths in the $ϕ \to e^{+} e^{-}$ and $ϕ \to K^{+} K^{-}$ channels

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

The invariant mass spectra of $ϕ \to K^{+} K^{-}$ are measured in 12 GeV $p + A$ reactions in order to search for the in-medium modification of $ϕ$ mesons. The observed $K^{+} K^{-}$ 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…

Evidence for in-medium modification of the $ϕ$ meson at normal nuclear density

R. Muto, H. En'yo, M. Naruki +23

Invariant mass spectra of e+e- pairs have been measured in 12 GeV p+A reactions to detect possible in-medium modification of vector mesons. Copper and carbon targets are used to st…

Observation of $ρ / ω$ Meson Modification in Nuclear Matter

K. Ozawa, H. En'yo, H. Funahashi +21

We have measured invariant mass spectra of electron-positron pairs in the target rapidity region of 12GeV p+A reactions. We have observed a significant difference in the mass spect…
