Novel Scaling Behavior for the Multiplicity Distribution under Second-Order Quark-Hadron Phase Transition
نویسندگان
چکیده
Deviation of the multiplicity distribution Pq in small bin from its Poisson counterpart pq is studied within the Ginzburg-Landau description for second-order quark-hadron phase transition. Dynamical factor dq ≡ Pq/pq for the distribution and ratio Dq ≡ dq/d1 are defined, and novel scaling behaviors between Dq are found which can be used to detect the formation of quark-gluon plasma. The study of dq and Dq is also very interesting for other multiparticle production processes without phase transition. PACS number(s): 05.70.Fh, 05.40.+j, 12.38.Mh

Multiplicity distribution in small bins is studied for second-order phase transition. Novel scaling behavior is found which can be used to detect the formation of quark-gluon plasma. Multiplicity distribution is one of the most important and most easily accessable experimental quantities in high energy leptonic and hadronic collisions. From the well-known KNO scaling and its violation [1, 2] to...

Multiplicity distribution in small bins is studied within the Ginzburg-Landau description for first-order quark-hadron phase transition. Direct comparison of the distribution with a Poisson one (with the same average) is made. Dynamical factor dq for the distribution and ratio Dq ≡ dq/d1 are studied, and novel scaling behaviors between Dq are found which can be used to detect the formation of q...
متن کاملMultiplicity difference correlators under first-order QGP phase transition
The multiplicity difference correlators between two well-separated bins in high-energy heavy-ion collisions are studied as a means to detect evidence of a first-order quark-hadron phase transition. Analytical expressions for the scaled factorial moments of multiplicity difference distribution are obtained for small bin size δ with mean multiplicity in the bin s ≤ 1.0 within Ginzburg-Landau desc...
متن کاملQuark-hadron phase transition with surface fluctuation
The effect of surface fluctuation on the observables of quark-hadron phase transition is studied. The Ginzburg-Landau formalism is extended by the inclusion of an extra term in the free energy that depends on the vertical displacements from a flat surface. The probability that a bin has a particular net displacement is determined by lattice simulation, where the physics input is color confineme...
