Description
The proton-proton correlation functions are widely used to infer the baryon
source spatial and temporal extents in relativistic heavy-ion collisions. Due to
the space-momentum correlation, information on collectivity can also be extracted from the correlation functions.
In this talk, we will present the first measurement of proton-proton correlation functions in Au+Au collisions at $\sqrt{s_{_{\rm NN}}}$ = 3.0 GeV, recorded by the STAR
experiment with a FXT target mode at RHIC in the year 2018. Results of the
collision centrality, proton transverse momenta, and rapidity dependence will
be presented. The experimental results will be compared with the calculations
from UrQMD transport model. In addition, a systematic energy dependence of
the proton-proton correlation functions will be discussed.
