We investigate effects of cluster particle correlations on two- and three-particle azimuth correlator observables sensitive to local strong parity violation. use two-particle angular correlation measurements as inputs estimate the magnitudes with straightforward assumptions. found that in STAR experiment can be entirely accounted for by together a reasonable range anisotropy nonperipheral collisions. Our result suggests new physics, such violation, may not required explain data.
We trace the development of elliptic anisotropy (v2) via parton-parton collision history in two transport models. The parton v2 is studied as a function number collisions each Au+Au and d+Au at sNN =200 GeV. It found that majority comes from anisotropic escape probability partons, with no fundamental difference low high transverse momenta. contribution to hydrodynamic-type collective flow be small. Only when cross-section set unrealistically large does this start take over. Our findings...
Under the approximate chiral symmetry restoration, quark interactions with topological gluon fields in quantum chromodynamics can induce a chirality imbalance and parity violation local domains. An electric charge separation (CS) could be generated along direction of strong magnetic field (B), phenomenon called effect (CME). CS measurements by azimuthal correlators are contaminated major backgrounds from elliptic flow anisotropy (v_{2}). Isobaric _{44}^{96}Ru+_{44}^{96}Ru...

It is found that Ru+Ru/Zr+Zr ratios $N_{\rm ch}$ distributions $ε_{2}$ mid-central exquisitely sensitive to type (skin vs.~halo). state-of-the-art calculations by energy density functional theory (DFT) favor halo-type can soon be confronted...
Transverse momentum ($p_{T}$) generation in relativistic heavy ion collisions is sensitive to the initial geometry and final-state bulk evolution. We demonstrate with hydrodynamic calculations that mean $p_T$ ratio ($R_{\langle p_{T}\rangle}$) between highly similar isobar $^{96}_{44}$Ru+$^{96}_{44}$Ru $^{96}_{40}$Zr+$^{96}_{40}$Zr insensitive evolution remains small difference nuclear structure (neutron skin deformation) Ru Zr nuclei.We further find deformation can produce an...
Particle production in ultrarelativistic heavy ion collisions depends on the details of nucleon density distributions colliding nuclei. We demonstrate that charged hadron multiplicity isobaric at energies provide a novel approach to determine poorly known neutron and thus skin thickness finite nuclei, which can turn put stringent constraints nuclear symmetry energy.
Charged hadrons (0.15 < p⊥ 4 GeV/c) associated with a large trigger particle (4 ptrig⊥ 6 are statistically reconstructed in the acceptance STAR TPC for p+p and Au+Au collisions at GeV. Preliminary results on transverse momentum distributions of these presented, separately near away side from particle. An increase multiplicity total scalar to central is observed. The away-side distribution found be significantly softened respect collisions. consistent modification jets heavy-ion RHIC.
We propose a novel method to search for the chiral magnetic effect (cme) in heavy ion collisions.We argue that relative strength of field (mainly from spectator protons and responsible cme) with respect reaction plane participant is opposite elliptic flow background arising fluctuating geometry.This behavior single collision system, hence small systematic uncertainties, can be exploited extract possible cme signal background.The applied existing data at rhic, outcome which discussed.
Within A Multi-Phase Transport model, we investigate decorrelation of event planes over pseudorapidity and its effect on azimuthal anisotropy measurements in relativistic heavy-ion collisions. The increases with increasing {\eta} gap between particles used to reconstruct the planes. third harmonic are found even anticorrelated forward backward rapidities, source which may root opposite orientation collision geometry triangularities. call into question anisotropic flow designed reduce nonflow...
We investigate the effect of resonance decays on three-particle correlator charge separation observable in search for chiral magnetic effect, using a simple simulation with realistic inputs. find that can largely account measured signal. suppress elliptic flow ($v_2$) background by zero event-by-event $v_2$ (or via mixed-event technique). is suppressed, but not eliminated as naively anticipated. identify reason to be non-identicalness and final-state particle's induced correlation between...
Correlation measurements with respect to the spectator and participant planes in relativistic heavy ion collisions were proposed extract chiral magnetic effect (CME) from background dominated azimuthal correlators. This paper investigates effects of two- three-particle nonflow correlations on extracted CME signal fraction, $f_{\text{CME}}$. It is found, guided by a multiphase transport (AMPT) model jet interaction generator (HIJING) together experimental data, that amount approximately...
Neutron skin thickness ($\mathrm{\ensuremath{\Delta}}{r}_{\mathrm{np}}$) of nuclei and the inferred nuclear symmetry energy are critical importance to physics astrophysics. It is traditionally measured by processes with significant theoretical uncertainties. We recently proposed an indirect measurement $\mathrm{\ensuremath{\Delta}}{r}_{\mathrm{np}}$ charged hadron multiplicities in central isobaric collisions at relativistic energies, which sensitive densities. In this Letter, we propose a...

Multi-parton color connection are included these simulations which have been perceived to produce collectivity final-state particles. Meanwhile, contributions from genuine few-body nonflow correlations, not flow behavior, known...

ABSTRACT Plasma proteins are considered an important indicator for cancer diagnosis and prognosis. Currently, commonly used detection methods unable to achieve rapid highly sensitive of plasma proteins, making them insufficient meet the demands high‐sensitivity screening. To address this issue, we propose a method using surface‐enhanced Raman spectroscopy (SERS) based on particulate triacetate cellulose (TCA), referred as TCA‐SERS. verify feasibility TCA‐SERS liver (LC) screening, analyzed...

The hexadecapole deformation (${\ensuremath{\beta}}_{4}$) of the $^{238}\mathrm{U}$ nucleus has not been determined because its effect is overwhelmed by those from nucleus' large quadrupole (${\ensuremath{\beta}}_{2}$) in nuclear electric transition measurements. In this Letter, we identify nonlinear response anisotropy to ellipticity relativistic $\mathrm{U}+\mathrm{U}$ collisions that solely sensitive ${\ensuremath{\beta}}_{4}$ and insensitive ${\ensuremath{\beta}}_{2}$. We demonstrate...
