We explore the influence of three-particle interactions, in either the initial or final state, on the collision rate in a high temperature plasma, and on the rate of quark and anti-quark pair (flavor) production. When the interactions are taken to be screened at the Debye wave number q d...
1 Introduction Proton–proton scattering at very high energy taking into account the quark structure of proton located is becoming in the centre of the attention of researchers, especially with many measurements of proton–proton scattering cross sec- tions. Different theoretical models are suggested ...
Three-body hadronic models with separable pairwise interactions are for- mulated and solved to calculate resonance masses and widths of L = 0 N∆ and ∆∆ dibaryons using relativistic kinematics. For N ∆, I(JP ) = 1(2+) and 2(1+) resonances slightly below threshold are found ...

Experimental studies of the collisions of heavy nuclei at relativistic energies have established the properties of the quark–gluon plasma (QGP), a state of hot, dense nuclear matter in which quarks and gluons are not bound into hadrons1,2,3,4. In this state, matter behaves as a nearly ...
we obtain five dual models with gauge group. These ten models have different gauge coupling relations at string scale. The highest wrapping number is 4, and one of the models contains no filler O6-planes. Moreover, we discuss in detail the particle spectra, the composite particles through stro...
