Influence of in-medium mass width on Hanbury Brown-Twiss correlation strength

The interactions of particles with medium may lead to a nonzero in-medium mass width of the particles and cause them to have different masses in the medium. In this letter, we investigate the influence of the in-medium mass width on the strength of Hanbury Brown-Twiss (HBT) correlation in high-energy heavy-ion collisions. It is found that the strength decreases with in-medium mass width of identical bosons. This influence are more significant for the boson with heavier mass and decreases with increasing particle momentum.
