First measurement of $ϕ$ 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 $ϕ$ meson in 30 GeV proton-nucleus interactions on carbon and copper targets via the di-electron decay channel. The measur…

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

Gabor Balassa, Kazuya Aoki, Philipp Gubler +3

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

Cross section Measurements for $^{12}$ C $(K^{-}, K^{+} Ξ^{-})$ and $^{12}$ C $(K^{-}, K^{+} ΛΛ)$ Reactions at 1.8 GeV $/ c$

Woo Seung Jung, Yudai Ichikawa, Byung Min Kang +30

We present a measurement of the production of $Ξ^{-}$ and $ΛΛ$ in the $^{12}$ C $(K^{-}, K^{+})$ reaction at an incident beam momentum of 1.8 GeV/ $c$ , based on high-statistics dat…

Separating the transverse and longitudinal modes of $ϕ$ , $ρ$ , $K^{*}$ 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…

Identifying the transverse and longitudinal modes of the $K^{*}$ and $K_{1}$ mesons through their angular dependent decay modes

In Woo Park, Hiroyuki Sako, Kazuya Aoki +2

Observing the mass shifts of chiral partners will provide invaluable insight into the role of chiral symmetry breaking in the generation of hadron masses. Because both the $K^{*}$ an…

Observation of Coulomb-assisted nuclear bound state of $Ξ^{-}$ - $^{14}$ N system

S. H. Hayakawa, K. Agari, J. K. Ahn +95

In an emulsion-counter hybrid experiment performed at J-PARC, a $Ξ^{-}$ absorption event was observed which decayed into twin single- $Λ$ hypernuclei. Kinematic calculations enabled a…

B-meson production at forward and backward rapidity in $p$ + $p$ and Cu+Au collisions at $s_{_{N N}}$ =200 GeV

C. Aidala, N. N. Ajitanand, Y. Akiba +456

The fraction of $J / ψ$ mesons which come from B-meson decay, $F_{B \to J / ψ}$ , is measured for J/ $ψ$ rapidity \mbox{ $1.2 < ∣ y ∣ < 2.2$ } and $p_{T} > 0$ in $p$ + $p$ and Cu+Au c…

Towards a novel laser-driven method of exotic nuclei extraction-acceleration for fundamental physics and technology

Mamiko Nishiuchi, Hironao Sakaki, Katsuhisa Nishio +20

The measurement of properties of exotic nuclei, essential for fundamental nuclear physics, now confronts a formidable challenge for contemporary radiofrequency accelerator technolo…
