Here we address the question regarding the nature of quark gluon plasma (QGP), whether it is a liquid or strongly coupled plasma (SCP), using two different phenomenological models, namely quasi-particle model (qQGP) and strongly coupled quark gluon plasma (SCQGP). First we compare these two models, both of which explains the results of lattice simulation of quantum chromodynamics, as a function...

The possibility of η ′ having a gluonic admixture is still not excluded. In fact, the anomalous coupling of gluonic component of η ′ may play an important role towards understanding the unexpectedly large branching ratio for B → η ′ X s reported by CLEO. We point out that the η ′ gluonic component may be as large as 26 % by analysing the latest experimental data.

It is suggested that the inner energetic engine of Gamma ray burst (GRB) may be the result of the transition of normal hadron to quark-gluon plasma (QGP) in rapidly-rotating and spin-down newborn neutron star. When such a nascent neutron star slows down through dipole electromagnetic and quadruple gravitational radiation, the increasing center density may reach the QCD transition density, i.e.,...

5 v 1 2 9 A ug 1 99 4 REPRESENTATIONS OF CLIFFORD ALGEBRAS AND ITS APPLICATIONS

A real representation theory of real Clifford algebra has been studied in further detail, especially in connection with Fierz identities. As its application, we have constructed real octonion algebras as well as related octonionic triple system in terms of 8-component spinors associated with the Clifford algebras C(0, 7) and C(4, 3).
