Staggered Diquarks for Singly Heavy Baryons
In the staggered fermion formulation of lattice QCD, we construct diquark operators which are to be embedded in singly heavy baryons. The group theoretical connections between continuum and lattice staggered diquark representations are established.
متن کاملComparing the drag force on heavy quarks in N = 4 super-Yang-Mills theory and QCD
Computations of the drag force on a heavy quark moving through a thermal state of strongly coupled N = 4 super-Yang-Mills theory have appeared recently [1, 2, 3]. I compare the strength of this effect between N = 4 gauge theory and QCD, using the static force between external quarks to normalize the ’t Hooft coupling. Comparing N = 4 and QCD at fixed energy density then leads to a relaxation ti...
متن کاملWounded Quarks and Diquarks in Heavy Ion Collisions
A model in which the soft collisions of the nucleon are described in terms of interactions of its two constituents (a quark and a diquark) is proposed. When adjusted to describe precisely the elastic proton-proton scattering data and supplemented with the idea of wounded constituents, the model accounts rather well for the centrality dependence of particle production in the central rapidity reg...
متن کاملV.V.Braguta and A.E.Chalov PAIR PRODUCTION OF DOUBLY HEAVY DIQUARKS
Braguta V.V. and Chalov A.E. Pair production of doubly heavy diquarks: IHEP Preprint 2000-56. – Protvino, 2000. – p. 12, figs. 4, refs.: 6. We analytically calculate the total and differential cross sections for the pair production of doubly heavy diquarks in the framework of diquark model. The processes of electron-positron and quarkantiquark annihilations are considered. The fractions of doub...
متن کاملDrag force in AdS/CFT
The AdS/CFT correspondence and a classical test string approximation are used to calculate the drag force on an external quark moving in a thermal plasma of N = 4 superYang-Mills theory. This computation is motivated by the phenomenon of jet-quenching in relativistic heavy ion collisions.
