Production and Decay Dynamics of the Charmed Baryon Λ c + in e + e − Annihilations near Threshold

M. Ablikim, Mikhail N. Achasov, P. Adlarson, X. Ai et autres

The study of the charmed baryons is crucial for investigating the strong and weak interactions in the standard model and for gaining insights into the internal structure of baryons. In an e + e − experiment, the lightest charmed baryon, Λ c …

Precision Measurement of Net-Proton-Number Fluctuations in Au + Au Collisions at RHIC

J. Adam, L. Adamczyk, I. Aggarwal, M. M. Aggarwal et autres

We report precision measurements on cumulants (C_{n}) and factorial cumulants (κ_{n}) of (net) proton number distributions up to fourth order in Au+Au collisions over center-of-mass energies sqrt[s_{NN}]=7.7-27 GeV from phase II of the Beam Energy Scan program at RHIC. (Anti)protons are selected …

Onset of Constituent Quark Number Scaling in Heavy-Ion Collisions at RHIC

J. Adam, L. Adamczyk, I. Aggarwal, M. M. Aggarwal et autres

Partonic collectivity is one of the necessary signatures for the formation of quark-gluon plasma in high-energy nuclear collisions. Number of constituent quarks (NCQ) scaling has been observed for hadron elliptic flow ${v}_{2}$ in top energy nuclear collisions at the Relativistic Heavy Ion …

Observation of the Electromagnetic Field Effect via Charge-Dependent Directed Flow in Heavy-Ion Collisions at the Relativistic Heavy Ion Collider

M. I. Abdulhamid, B. E. Aboona, J. Adam, Joseph R. Adams et autres

The deconfined quark-gluon plasma (QGP) created in relativistic heavy-ion collisions enables the exploration of the fundamental properties of matter under extreme conditions. Noncentral collisions can produce strong magnetic fields on the order of 1018 G , which offers a probe into the …

Results on Elastic Cross Sections in Proton-Proton Collisions at $\sqrt{s} = 510$ GeV with the STAR Detector at RHIC

STAR Collaboration, M. I. Abdulhamid, B. E. Aboona, J. Adam et autres

We report results on an elastic cross section measurement in proton-proton collisions at a center-of-mass energy $\sqrt{s}=510$ GeV, obtained with the Roman Pot setup of the STAR experiment at the Relativistic Heavy Ion Collider (RHIC). The elastic differential cross section is measured …

Energy Dependence of Intermittency for Charged Hadrons in Au+Au Collisions at RHIC

STAR Collaboration, M. I. Abdulhamid, B. E. Aboona, J. Adam et autres

Density fluctuations near the QCD critical point can be probed via an intermittency analysis in relativistic heavy-ion collisions. We report the first measurement of intermittency in Au$+$Au collisions at $\sqrt{s_\mathrm{_{NN}}}$ = 7.7-200 GeV measured by the STAR experiment at the Relativistic Heavy …

Pair invariant mass to isolate background in the search for the chiral magnetic effect in Au + Au collisions at sNN=200 GeV

Mohamed S. Abdallah, J. Adam, L. Adamczyk, Joseph R. Adams et autres

Quark interactions with topological gluon configurations can induce local chirality imbalance and parity violation in quantum chromodynamics, which can lead to the chiral magnetic effect (CME)---an electric charge separation along the strong magnetic field in relativistic heavy-ion collisions. The CME-sensitive azimuthal correlator …

Differential measurements of jet substructure and partonic energy loss in Au + Au collisions at sNN=200 GeV

M. S. Abdallah, B. E. Aboona, J. Adam, L. Adamczyk et autres

QCD jets initially produced in relativistic heavy-ion collisions propagate through the quark-gluon plasma and act as tomographic probes of that dense medium. Measurements by the STAR Collaboration employ differential measurements of partonic energy loss to suggest that hard fragmenting jets at RHIC …

Tomography of Ultra-relativistic Nuclei with Polarized Photon-gluon Collisions

STAR Collaboration, Mohamed S. Abdallah, B. E. Aboona, J. Adam et autres

A linearly polarized photon can be quantized from the Lorentz-boosted electromagnetic field of a nucleus traveling at ultra-relativistic speed. When two relativistic heavy nuclei pass one another at a distance of a few nuclear radii, the photon from one nucleus may interact …

Search for the Chiral Magnetic Effect via Charge-Dependent Azimuthal Correlations Relative to Spectator and Participant Planes in Au+Au Collisions at sqrt[s_{NN}]=200 GeV.

M. S. Abdallah, J. Adam, L. Adamczyk, Joseph R. Adams et autres

The chiral magnetic effect (CME) refers to charge separation along a strong magnetic field due to imbalanced chirality of quarks in local parity and charge-parity violating domains in quantum chromodynamics. The experimental measurement of the charge separation is made difficult by the …

Search for the chiral magnetic effect with isobar collisions at s N N = 200 GeV by the STAR Collaboration at the BNL Relativistic Heavy Ion Collider

M. S. Abdallah, B. E. Aboona, J. Adam, L. Adamczyk et autres

The chiral magnetic effect (CME) is predicted to occur as a consequence of a local violation of $\mathcal{P}$ and $\mathcal{C}P$ symmetries of the strong interaction amidst a strong electromagnetic field generated in relativistic heavy-ion collisions. Experimental manifestation of the CME involves a …

Global Λ -hyperon polarization in Au + Au collisions at s NN = 3 GeV

M. S. Abdallah, B. E. Aboona, J. Adam, L. Adamczyk et autres

Global hyperon polarization, ${\overline{P}}_{\mathrm{H}}$, in $\mathrm{Au}+\mathrm{Au}$ collisions over a large range of collision energy, $\sqrt{{s}_{\mathrm{NN}}}$, was recently measured and successfully reproduced by hydrodynamic and transport models with intense fluid vorticity of the quark-gluon plasma. While na\"{\i}ve extrapolation of data trends suggests a …
