DESCRIPTION:Speakers: Haoyang Qi (Peking University)\nStrong nuggets with 
 a baryon number of A=10^10-10^30 could be able to survive from the cosmic 
 separation of the QCD phases\, provided the transition from strange quark 
 matter to strangeon matter is accounted for\, thereby evading evaporation 
 in the early Universe. Such strangeon nuggets may serve as a dark matter c
 andidate within particle standard model. We formulate the corresponding ph
 ase transition of cosmic strange matter\, establishing a parameter space w
 hich reasonably accommodates observational constraints on the dark-to-lumi
 nous matter ratio and the mass-radius relation\, as well as tidal deformab
 ility of compact objects.\n\nhttps://indico.itp.ac.cn/event/419/contributi
