Transient velocity measurement of impact object via parallel low sampling rate sub-band signals processing

Shiyu Zhen, Lijun Xu, Hongyao Li, Xiaoyan Duan et autres

Abstract Doppler impact intensity measurement is widely applied in railway transportation and aerospace engineering for enhancing equipment robustness, reliability, and accelerometer accuracy. Data acquisition and processing still present challenges due to high frequency, non-stationarity, and large data volume. This study presents an …

Search for a dark baryon in the Ξ − → π − + i n v i s i b l e decay

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

A search for a dark baryon is performed for the first time in the two-body decay $Ξ^-\rightarrowπ^-+{\rm invisible}$ using $(10.087\pm0.044)\times10^{9}$ $J/ψ$ events collected at a center-of-mass energy of $\sqrt{s}=3.097\,\mbox{GeV}$ with the BESIII detector at the BEPCII collider. No significant signal is observed, …

Temperature measurement of Quark-Gluon plasma at different stages

B. E. Aboona, J. Adam, L. Adamczyk, I. Aggarwal et autres

Abstract In a Quark-Gluon Plasma (QGP), the fundamental building blocks of matter, quarks and gluons, are under extreme conditions of temperature and density. A QGP could exist in the early stages of the Universe, and in various objects and events in the …

Production and Decay Dynamics of the Charmed Baryon $Λ_c^+$ in $e^+e^-$ Annihilations near Threshold

BESIII Collaboration, M. Ablikim, Mikhail N. Achasov, P. Adlarson 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, $Λ_c^+$, can be produced in …

Light nuclei femtoscopy and baryon interactions in 3 GeV Au+Au collisions at RHIC

B. E. Aboona, J. Adam, L. Adamczyk, I. Aggarwal et autres

We report the measurements of proton-deuteron ( p - d ) and deuteron-deuteron ( d - d ) correlation functions in Au+Au collisions at s NN = 3 GeV using fixed-target mode with the STAR experiment at the Relativistic Heavy-Ion Collider (RHIC). …

Search for the chiral magnetic wave using anisotropic flow of identified particles at energies available at the BNL Relativistic Heavy Ion Collider

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

The chiral magnetic wave (CMW) has been theorized to propagate in the deconfined nuclear medium formed in high-energy heavy-ion collisions and to cause a difference in elliptic flow (${v}_{2}$) between negatively and positively charged hadrons. Experimental data consistent with the CMW have …

Higher-order cumulants and correlation functions of proton multiplicity distributions in sNN=3 GeV Au+Au collisions at the RHIC STAR experiment

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

Various models of the QCD phase diagram favor a first-order phase transition to quark-gluon plasma, and therefore a critical endpoint which could manifest itself in measurable fluctuations and correlations. The authors report measurements of the moments of the net proton multiplicity fluctuations …

Azimuthal transverse single-spin asymmetries of inclusive jets and identified hadrons within jets from polarized pp collisions at s=200 GeV

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

The STAR Collaboration reports measurements of the transverse single-spin asymmetries, ${A}_{N}$, for inclusive jets and identified ``hadrons within jets'' production at midrapidity from transversely polarized $pp$ collisions at $\sqrt{s}=200\text{ }\text{ }\mathrm{GeV}$, based on data recorded in 2012 and 2015. The inclusive jet …

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 …

Measurement of e + e − Momentum and Angular Distributions from Linearly Polarized Photon Collisions

J. Adam, L. Adamczyk, J. R. Adams, J. K. Adkins et autres

The Breit-Wheeler process which produces matter and antimatter from photon collisions is experimentally investigated through the observation of 6085 exclusive electron-positron pairs in ultraperipheral $\mathrm{Au}+\mathrm{Au}$ collisions at $\sqrt{{s}_{NN}}=200\text{ }\text{ }\mathrm{GeV}$. The measurements reveal a large fourth-order angular modulation of $\mathrm{cos}4\mathrm{\ensuremath{\Delta}}\ensuremath{\phi}=(16.8\ifmmode\pm\else\textpm\fi{}2.5)%$ and smooth …

We report new STAR measurements of the single-spin asymmetries ${A}_{L}$ for ${W}^{+}$ and ${W}^{\ensuremath{-}}$ bosons produced in polarized proton-proton collisions at $\sqrt{s}=510\text{ }\text{ }\mathrm{GeV}$ as a function of the decay-positron and decay-electron pseudorapidity. The data were obtained in 2013 and correspond to …
