First measurement of $I ¨ $ meson production in 30 GeV proton-nucleus reactions via di-electron decay at J-PARC

PARC E16 collaboration, Satomi Nakasuga, Yuhei Morino +44

We present the first measurement of the production of the $I ¨ $ meson in 30 GeV proton-nucleus interactions on carbon and copper targets via the di-electron decay channel. The measu…

Studying the in-medium $I ¨ $ meson spectrum through kaons in proton-nucleus reactions

Gabor Balassa, Kazuya Aoki, Philipp Gubler +3

Exploring the mass modifications of $I ¨ $ mesons in nuclei provides insights into the nature of strongly interacting matter. Specifically, $I ¨ $ meson mass shifts can be related to t…

Velocity dependence of the mass modifications of $I ¨ $ and $I ¨ $ mesons in 12 GeV $p + A$ reactions

Wataru Nakai, Kazuya Aoki, Junsei Chiba +26

This study measured the invariant mass spectra of $I ¨ $ and $I ¨ $ mesons in the $e^{+} e^{-}$ decay channel for 12 GeV (12.9 GeV/ $c$ ) $p + C$ and $p + Cu$ reactions ($\sqrt{…

Separating the transverse and longitudinal modes of $I ¨ $ , $I ¨ $ , $K^{*}$ and $K_{1}$ mesons through their angular-dependent two-body decay modes

In Woo Park, Hiroyuki Sako, Kazuya Aoki +2

The mass shift a spin-1 particle moving in the nuclear medium will depend on its polarization direction. To study polarization-independent mass shifts in the medium, we explore met…
