Comment:
Correlations and Fluctuations Measurements by STAR Experiment at RHIC
Daniel Wielanek for the STAR Collaboration

The STAR (Solenoidal Tracker at RHIC) experiment is conducted at the  
Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory.  
Originally designed to study the properties of the Quark-Gluon Plasma (QGP)  
and the nature of strongly interacting matter under extreme conditions  
similar to those in the early Universe, STAR's scope expanded with the  
initiation of the Beam Energy Scan program. This program broadened the  
investigation to include the region of high baryonic densities, making STAR  
an excellent tool for studying the phase diagram of strongly interacting  
matter.

This talk focuses on measurements of correlations and fluctuations performed  
by STAR. Fluctuation measurements are crucial for understanding the  
thermodynamic properties of QGP phase transitions, including the search for  
critical points. Femtoscopic measurements, which are based on the correlation 
 
of pairs of particles, allow us to explore the dynamics of the collision  
process. These measurements also enable the study of the final state  
interactions between various pairs of particles, which is essential for  
predicting the behavior of matter under extreme conditions, such as those  
inside neutron stars.

Daniel: I made few changes in the abstract: (i) Title; (ii) 2nd paragraph and 
 
(iii) removed the last line.  In addition, I would prefer to add some more  
specific statements regarding the measurements of fluctuations and  
correlations. For example, fluctuation (net-proton high moments) and  
correlations (pion femptoscopy). Once these suggestions are impleted, I sign  
off.
