Title: Practical considerations for measuring global spin alignment of vector mesons in relativistic heavy ion collisions

Abstract

Global spin alignment of vector mesons is a sensitive probe of system vorticity and particle production mechanism in relativistic heavy ion collisions. The measurement of global spin alignment is gaining increasing interest and deserves careful considerations. In this paper, we lay out a few practical issues that need to be taken care of when measuring global spin alignment of vector mesons. They are, the correction for event plane resolution, reconciling measurements made with different event planes, the correction for the effect of finite acceptance in pseudorapidity, and the consideration for measuring the azimuthal angle dependence. Furthermore insights and methodologies offered in this paper will help experiments to measure the global spin alignment properly and accurately.

Spin alignment of vector mesons in non-central A+Acollisions

Journal Article Liang, Zuo-Tang ; Wang, Xin-Nian - Physics Letters B

We discuss the consequence of global polarization of the produced quarks in non-central heavy-ion collisions on the spin alignment of vector mesons. We show that the alignment is quite different for different hadronization scenarios. These results can be tested directly by measuring the vector mesons' alignment through angular distributions of the decay products with respect to the reaction plane. Such angular distributions will give rise to azimuthal anisotropy v{sub 2} of the decay products in the collision frame. Constraints provided by the data on the azimuthal anisotropy of hadron spectra at RHIC points to a quark recombination scenario of hadronization.

Procedure for measuring photon and vector meson circular polarization variation with respect to the reaction plane in relativistic heavy-ion collisions

Journal Article Tang, A. H. ; Wang, G. - Physical Review C

The electromagnetic (EM) eld pattern created by spectators in relativistic heavy-ion collisions plants a seed of positive (negative) magnetic helicity in the hemisphere above (below) the reaction plane. Owing to the chiral anomaly, the magnetic helicity interacts with the fermionic helicity of the collision system, and causes photons emitted in upper- and lower-hemispheres to have different preferences in the circular polarization. Similar helicity separation for massive particles, due to the global vorticity, is also possible. In this paper, we lay down a procedure to measure the variation of the circular polarization w.r.t the reaction plane in relativistic heavy-ion collisions formore »« less

Impact of globally spin-aligned vector mesons on the search for the chiral magnetic effect in heavy-ion collisions

Journal Article Shen, Diyu ; Chen, Jinhui ; Tang, Aihong ; ... - Physics Letters. B

In high-energy heavy-ion collisions, the chiral magnetic effect (CME) is predicted to arise from the interplay between the chirality imbalance of quarks in the nuclear medium and the intense magnetic field, and will cause a charge separation along the magnetic field direction. While the search for the CME is still ongoing in experiments at Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC), the CME-sensitive observables need to be scrutinized to exclude the non-CME contributions. In this work, we examine the influence of globally spin-aligned ρ mesons on the γ₁₁₂ correlator, the R_Ψ₂(ΔS) correlator, and the signed balancemore »« less

First measurement of prompt and non-prompt D*⁺ vector meson spin alignment in pp collisions at $$\sqrt{s}$$ = 13 TeV

This letter reports the first measurement of spin alignment, with respect to the helicity axis, for D*⁺ vector mesons and their charge conjugates from charm-quark hadronisation (prompt) and from beauty meson decays (non-prompt) in hadron collisions. The measurements were performed at midrapidity (|y| < 0.8) as a function of transverse momentum (p_T) in proton–proton (pp) collisions collected by ALICE at the centre-of-mass energymore »« less

Spin alignment measurements of the K*{sup 0}(892) and {phi}(1020) vector mesons in heavy ion collisions at {radical}(s{sub NN})=200 GeV

Journal Article Abelev, B I ; Barannikova, O ; Betts, R R ; ... - Physical Review. C, Nuclear Physics

We present the first spin alignment measurements for the K*{sup 0}(892) and {phi}(1020) vector mesons produced at midrapidity with transverse momenta up to 5 GeV/c at {radical}(s{sub NN})=200 GeV at RHIC. The diagonal spin-density matrix elements with respect to the reaction plane in Au+Au collisions are {rho}{sub 00}=0.32{+-}0.04 (stat) {+-} 0.09 (syst) for the K*{sup 0} (0.8<p{sub T}<5.0 GeV/c) and {rho}{sub 00}=0.34{+-}0.02 (stat) {+-} 0.03 (syst) for the {phi} (0.4<p{sub T}<5.0 GeV/c) and are constant with transverse momentum and collision centrality. The data are consistent with the unpolarized expectation of 1/3 and thus no evidence is found for the transfermore »« less
