Charged-lepton identification at Belle~II

Belle II Collaboration, M. Abumusabh, I. Adachi +409

Effective particle identification capabilities are a strategic priority for the physics program of the Belle~II experiment. We describe the algorithms used at Belle~II for identify…

First evidence of $X (3872) \to π^{0} χ_{c 0} (1 P)$ and search for $X (3915) \to π^{0} χ_{c 1} (1 P)$

Belle, Belle II Collaborations, : +412

We search for the pionic transitions $X (3872) \to π^{0} χ_{c J} (1 P)$ $(J = 0, 1, 2)$ and $X (3915) \to π^{0} χ_{c 1}$ in $B^{+} \to π^{0} χ_{c J} K^{+}$ decays using the Belle and Belle~II data samples c…

Measurement of mixing-induced CP violation in the decay $B^{0} \to π^{0} π^{0}$

Belle II Collaboration, M. Abumusabh, I. Adachi +437

Measurements of charge-parity (CP) violation in quark transitions provide stringent tests of the current theory and sensitive probes of particles or interactions beyond it. We repo…

Probing Late-Stage Hadronic Interactions at High Baryon Density via $K^{* 0}$ Production in the RHIC Beam Energy Scan Program

STAR Collaboration, B. E. Aboona, J. Adam +360

A precision measurement of the $K^{* 0}$ meson yield is reported in Au+Au collisions at $s_{N N} = 7.7, 11.5, 14.6, 19.6,$ and $27 GeV$ using the high-statistic…

Evidence of Spin-Interference Effects in Exclusive $J / ψ \to e^{+} e^{-}$ Photoproduction in Ultraperipheral Heavy-Ion Collisions

The STAR Collaboration

We report the first evidence of spin interference in exclusive $J / ψ \to e^{+} e^{-}$ photoproduction in ultraperipheral heavy-ion collisions at STAR at $s_{N N} = 200$ ~GeV. In Au+A…

Study of Central Exclusive Production of $π^{+} π^{-}$ , $K^{+} K^{-}$ and $p p ˉ$ Pairs in Proton-Proton Collisions at $s = 510$ GeV with the STAR Detector at RHIC

STAR Collaboration, B. E. Aboona, J. Adam +378

We report on the first measurement of the Central Exclusive Production process in proton-proton collisions: $pp \to p h^{+} h^{-} p$ (where $h = π, K, p$ ) at the center-of-…

Belle II Collaboration, M. Abumusabh, I. Adachi +367

We observe the radiative decay $D_{s 0}^{*} (2317)^{+} \to D_{s}^{*+} γ$ for the first time, with a significance exceeding $10$ standard deviations. The signal is found in the contin…

Beam-energy dependence of correlations between mean transverse momentum and anisotropic flow of charged particles in Au+Au collisions at RHIC

The STAR Collaboration

The correlation between the mean transverse momentum, $[p_{T}]$ , and the squared anisotropic flow, $v_{n}^{2}$ , on an event-by-event basis has been suggested to be influen…
