Abstract

Abstract: Properties of strange quark matter (SQM) have been studied as diquark matter with diquark correlation. The dense SQM is under strong magnetic field due to electroweak interaction of quarks. Here it is suggested that u, d, s quarks get correlated to form diquark matter of different flavors. The diquarks are suggested to behave like quasiparticles under the influence of strong magnetic field inside the dense quark matter. In the current work diquarks are described as the composite fermions which behave like quasiparticle under the strong magneticfield in an analogy with the electrons behaving in strong magnetic field. The thermodynamic potential for SQM has been estimated and behavior is studied with respect to chemical potential. The equation of state and the velocity of sound through SQM are also studied. Some interesting observations are made. It is suggested that the composite fermion picture of diquark correlation lowers the binding energy of the system making the SQM a more stable state. Abstract : Strange quark matter (SQM) is described as diquark matter consisting of [ud], [us], and [ss] diquark correlations. Under the influence of strong magnetic field in dense SQM, diquarks behave like composite fermions (quasiparticles). Thermodynamic properties and velocity of sound show interesting behavior. The diquark correlation lowers the binding energy of SQM making the system more stable.
