Higher Moments of Net-proton Multiplicity Distributions at RHIC

The STAR collaboration Aggarwal, M.M. ; Ahammed, Z. ; Alakhverdyants, A.V. ; et al.

We report the first measurements of the kurtosis (\kappa), skewness (S) and variance (\sigma^2) of net-proton multiplicity (N_p - N_pbar) distributions at midrapidity for Au+Au collisions at \sqrt(s_NN) = 19.6, 62.4, and 200 GeV corresponding to baryon chemical potentials (\mu_B) between 200 - 20 MeV. Our measurements of the products \kappa \sigma^2 and S \sigma, which can be related to theoretical calculations sensitive to baryon number susceptibilities and long range correlations, are constant as functions of collision centrality. We compare these products with results from lattice QCD and various models without a critical point and study the \sqrt(s_NN) dependence of \kappa \sigma^2. From the measurements at the three beam energies, we find no evidence for a critical point in the QCD phase diagram for \mu_B below 200 MeV.

Jets of nuclear matter in He-A(T) inelastic collisions at 4.5-A-GeV/c.

Besliu, C. ; Jipa, A. ; Zaharia, R. ; et al.
Eur.Phys.J.A 1 (1998) 65-75, 1998.
Inspire Record 467239 DOI 10.17182/hepdata.43769

The problem of the nuclear matter jets in nucleus-nucleus collisions at 4.5 A GeV/c is discussed. The global analysis of experimental data, namely the sphericity tensor, is used to evidence such jets.

Production of neutral strange particles in p Ar, p Xe and anti-p Xe collisions at 200-GeV

Z.Phys.C 50 (1991) 31-36, 1991.
Inspire Record 28958 DOI 10.17182/hepdata.15007

The production of neutral strange particles (K0, Λ) inp Ar,pXe and\(\bar p\)Xe collisions at 200 GeV is investigated in the NA5 experiment using a streamer chamber at the CERN SPS. Results are presented on inclusive cross sections, average multiplicities, and on rapidity and transverse momentum distributions of neutral strange particles.

Bose-Fermi U(6/2J+1) Supersymmetries And High-Spin Anomalies

Morrison, I. ; Jarvis, Peter D. ;
Nucl.Phys.A 435 (1985) 461-476, 1985.
Inspire Record 212932 DOI 10.17182/hepdata.17659

A supersymmetric extension of the interacting boson model (IBM) is constructed to describe high-spin anomalies in both even- and odd-mass spectra of the Hg, Pt region (190 ⩽ A ⩽ 200). Supergroup chains such as U ( 6 2j + 1 ) ⊃ Osp ( 6 2j + 1 ) ⊃ O (6) × Sp ( 6 2j + 1 )… U ( 6 2j + 1 ) ⊃ U ( 5 2j + 1 ) ⊃ Osp ( 5 2j + 1 )… incorporate a single j -shell fermion in addition to the usual “s” and “d” bosons ( L = 0 and L = 2). The orthosympletic supergroup reflects the strong pairing force in the subspace of the fermion intruder level. The model agrees favourably with experiment and microscopic calculation.
