     "Finite-Size-Finite-Time Scaling of Susceptibility Proxies Near the 
			      QCD Critical Point"

        /2016-os Zimányi Nehézionfizikai Téli Iskolával közös előadás/


Kivonatos ismertetés:
A major experimental theme at the Relativistic Heavy Ion Collider (RHIC), is 
the the measurement of observables that could signal the location and 
character of the critical endpoint (CEP) – the end point of the first-order 
coexistence curve in the temperature vs. baryon chemical potential (T, µB) 
plane of the phase diagram for Quantum Chromodynamics (QCD). I will discuss 
Finite-Size-Finite-Time Scaling of several RHIC measurements linked to the 
baryon number susceptibility, and show that they lead to scaling functions 
which provide a potent tool for locating and characterizing the CEP. A recent 
estimate of the location of the CEP and the critical exponents used to 
characterize the order of its transition and its static and dynamic 
universality classes, will be presented as well.
