Cross sections of $η$ mesons in $p$$+$$p$ collisions at forward rapidity at $\sqrt{s}=500$ GeV and central rapidity at $\sqrt{s}=510$ GeV

U. Rajendra Acharya, A. Adare, C. Aidala, Y. Akiba et autres

We present the first measurements of the forward and midrapidity $η$-meson cross sections from $p$$+$$p$ collisions at $\sqrt{s}=500$ and $510$~GeV, respectively. We also report the midrapidity $η/π^0$ ratio at 510 GeV. The forward cross section is measured differentially in $η$-meson transverse momentum …

Search for Astrophysical Electron Antineutrinos in Super-Kamiokande with 0.01% Gadolinium-loaded Water

Masayuki Harada, K. Abe, C. Bronner, Y. Hayato et autres

Abstract We report the first search result for the flux of astrophysical electron antineutrinos for energies  ( 10 ) MeV in the gadolinium-loaded Super-Kamiokande (SK) detector. In 2020 June, gadolinium was introduced to the ultrapure water of the SK detector in …

Beam Energy and Centrality Dependence of Direct-Photon Emission from Ultrarelativistic Heavy-Ion Collisions

A. Adare, S. Afanasiev, C. Aidala, N. N. Ajitanand et autres

The PHENIX collaboration presents first measurements of low-momentum ($0.4<{p}_{T}<3\text{ }\text{ }\mathrm{GeV}/c$) direct-photon yields from $\mathrm{Au}+\mathrm{Au}$ collisions at $\sqrt{{s}_{NN}}=39$ and 62.4 GeV. For both beam energies the direct-photon yields are substantially enhanced with respect to expectations from prompt processes, similar to the yields …

Measurement of two-particle correlations with respect to second- and third-order event planes in Au + Au collisions at s NN = 200 GeV

We present measurements of azimuthal correlations of charged hadron pairs in $\sqrt{{s}_{\mathit{NN}}}=200$ GeV $\mathrm{Au}+\mathrm{Au}$ collisions for the trigger and associated particle transverse-momentum ranges of $1<{p}_{T}^{t}<10\phantom{\rule{4pt}{0ex}}\mathrm{GeV}/c$ and $0.5<{p}_{T}^{a}<10\phantom{\rule{4pt}{0ex}}\mathrm{GeV}/c$. After subtraction of an underlying event using a model that includes higher-order azimuthal anisotropy ${v}_{2}, …

Centrality-Dependent Modification of Jet-Production Rates in Deuteron-Gold Collisions at sNN=200 GeV

A. Adare, C. Aidala, N. N. Ajitanand, Y. Akiba et autres

Jet production rates are measured in p+p and d+Au collisions at sqrt[s_{NN}]=200 GeV recorded in 2008 with the PHENIX detector at the Relativistic Heavy Ion Collider. Jets are reconstructed using the R=0.3 anti-k_{t} algorithm from energy deposits in the electromagnetic calorimeter and …

Centrality dependence of low-momentum direct-photon production in Au + Au collisions at s N N = 200 GeV

A. Adare, S. Afanasiev, C. Aidala, N. N. Ajitanand et autres

Direct photons produced in relativistic heavy-ion collisions allow access to the state of matter during the collision, because they do not experience the strong interaction and can escape from the fireball without scattering. New data from the PHENIX experiment at RHIC show …
