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…

Medium-induced modification of azimuthal correlations of electrons from heavy-flavor hadron decays with charged particles in Pb-Pb collisions at sNN​=5.02​ TeV

ALICE Collaboration

The azimuthal-correlation distributions between electrons from the decays of heavy-flavor hadrons and associated charged particles in Pb-Pb collisions at sNN​​=5.02…

Toward a Direct Measurement of Partial Restoration of Chiral Symmetry at J-PARC E16 via Density-induced Chiral Mixing

Ren Ejima, Philipp Gubler, Chihiro Sasaki +1

The degeneracy of chiral partners is an ideal signal for measuring the restoration of the spontaneously broken chiral symmetry in QCD. In this work, we investigate the observabilit…

Measurement of the inclusive isolated-photon production cross section in pp and Pb−Pb collisions at sNN​​=5.02 TeV

ALICE Collaboration

The ALICE Collaboration at the CERN LHC has measured the inclusive production cross section of isolated photons at midrapidity as a function of the photon transverse momentum ($p_{…
