Erratum: Disappearance of partonic collectivity in √ sNN = 3 GeV Au+Au collisions at RHIC [Phys. Lett. B 827, 137003 (2022)] Open
We report on the measurements of directed flow v1 and elliptic flow v2 for hadrons (π±, K±, KS0, p, ϕ, Λ and Ξ−) from Au+Au collisions at sNN = 3 GeV and v2 for (π±, K±, p and p‾) at 27 and 54.4 GeV with the STAR experiment. While at the t…
Angstrom-scale ion-beam engineering of ultrathin buried oxides for quantum and neuro-inspired computing Open
Multilayer nanoscale systems incorporating buried ultrathin tunnel oxides, 2D materials, and solid electrolytes are crucial for next-generation logics, memory, quantum and neuro-inspired computing. Still, an ultrathin layer control at angs…

Erratum to: Determination of the strong coupling constant $${{\varvec{\alpha _{\mathrm{s}} (m_{\mathrm{Z}})}}}$$ in next-to-next-to-leading order QCD using H1 jet cross section measurements Open
The determination of the strong coupling constant $$\alpha _{\mathrm{s}} (m_{\mathrm{Z}})$$ from H1 inclusive and dijet cross section data [1] exploits perturbative QCD predictions in next-to-next-to-leading order (NNLO) [2–4]. An implemen…
Serving the flow of requests when flying around ground objects by aircraft in the “air taxi” mode Open
The scientific work solves the problem of organizing a route group flight of aircraft, when pre-flight planning is carried out only for the beginning of the flight, and then operational planning is carried out by analogy with a taxi. The p…

Exploring time like tranistions in <i>pp, πp</i> and <i>AA</i> reactions with HADES Open
Radiative transition of an excited baryon to a nucleon with emission of a virtual massive photon converting to dielectron pair (Dalitz decays) provides important information about baryon-photon coupling at low q 2 in timelike region. A pro…
PHENIX Experiment Highlights Open
Over sixteen yesrs of running the PHENIX experiment at RHIC has collected a wealth of data on proton-proton, proton-nucleus, and nucleusnucleus collisions at various collision energies. In this talk we present the most recent and exciting …
Correlations of μμ, eμ, and ee pairs in p+p collisions at s√=200 GeV and implications for cc¯ and bb¯ production mechanisms Open
PHENIX has measured the azimuthal correlations of muon pairs from charm and bottom semi-leptonic decays in p+p collisions at s√=200 GeV, using a novel analysis technique utilizing both unlike- and like-sign muon pairs to separate charm, bo…
PHENIX Measurements of Heavy Flavor in Small Systems Open
The study of heavy flavor production in proton-nucleus and nucleus-nucleus collisions is a sensitive probe of the hot and dense matter created in such collisions. Installation of silicon vertex detectors in the PHENIX experiment, and incre…
Recent Results from The Phenix Collaboration At RHIC Open
The PHENIX experiment at RHIC has collected a huge amount of data on proton-proton, proton-nucleus, and nucleus-nucleus collisions in a wide range of collision energies. The variety of observables which can be measured by the PHENIX detect…

Determination of the strong coupling constant $\alpha_s(M_Z)$ in next-to-next-to-leading order QCD using H1 jet cross section measurements Open
The strong coupling constant $\alpha_s(M_Z)$ is determined from inclusive jet and dijet cross sections in neutral-current deep-inelastic $ep$ scattering (DIS) measured at HERA by the H1 collaboration using next-to-next-to-leading order (NN…
Latest Heavy Flavor Results from the PHENIX Experiment at RHIC Open
Heavy quark production can be used as a stringent test of perturbative QCD in proton-proton collisions, and is a valuable reference for the study of heavy ion collisions. In nucleus-nucleus collisions, the measurement of heavy quark produc…
