Physical Review Letters
Abstract: We present a search for an invisible hidden-sector particle Xinv, produced in B0→D¯0Xinv and B±→hXinv decays, where h=π±, K±, Ds±, p±. The search is performed using e+e- collision data recorded with…
Physical Review D
Abstract: A sample of 365 fb−1 of (Formula presented) data collected by the Belle II experiment is used to measure the partial branching fractions of charmless semileptonic B meson decays and determine the…
Physics Letters B
Abstract: A precision measurement of the K ⁎0 meson yield is reported in Au+Au collisions at sNN=7.7,11.5,14.6,19.6, and 27 GeV using the high-statistics data sample collected by the STAR experiment during the…
Physical Review C
Abstract: High-energy, heavy-ion collisions can create local domains of chirality-imbalanced quarks, reflecting the topological features of quantum chromodynamics. The chiral magnetic effect (CME) predicts an…
Physics Letters B
Abstract: This article presents measurements of inclusive J / ψ production at midrapidity (| y | < 1.0) in Au+Au collisions at sNN=54.4 GeV with the STAR detector at the Relativistic Heavy Ion Collider. A…
Physical Review Letters
Abstract: We report the first evidence of spin interference in exclusive J/ψ→e+e- photoproduction in ultraperipheral heavy-ion collisions at STAR at √sNN=200 GeV. In Au+Au collisions, a negative cos(2φ)…
Physical Review Letters
Abstract: Precise experimental information on hyperon-nucleon interactions is scarce but of paramount importance to our understanding of the inner structure of compact stars. In this Letter, we report the first…
Physical Review Letters
Abstract: We report measurements of charmonium sequential suppression in Ru+Ru and Zr+Zr collisions at sNN=200 GeV with the STAR experiment at the Relativistic Heavy Ion Collider (RHIC). The inclusive yield…
Physical Review D
Abstract: We report decay-rate CP asymmetries of the singly-Cabibbo-suppressed decays Ξþc → Σþhþh− and Λþc → phþh−, with h ¼ K, π, measured using 428 fb−1 of eþe− collisions collected by the Belle II experiment…
Physical Review Letters
Abstract: We report the first observation of the radiative decay Ds0∗(2317)+→ Ds∗+γ with a statistical significance exceeding 10 standard deviations. The signal is observed in the continuum e+e-→cc¯ process,…
