Spinning Dragging Strings
We use the AdS/CFT correspondence to compute the drag force experienced by a heavy quark moving through a N = 4 SU(N) super Yang-Mills plasma at nonzero temperature and R-charge chemical potential and at large ’t Hooft coupling. We resolve a discrepancy in the literature between two earlier studies of such quarks. In addition, we consider small fluctuations of the spinning strings dual to these...
متن کاملQCD strings with spinning quarks
A consistent description of spin within a QCD string theory has been sought for many years. The addition of dynamical spin to the bosonic string led to the development of supersymmetry and superstring theory [1]. Such theories are more realistic as unified theories of elementary particle physics than as phenomenological descriptions of hadronic states. A more realistic description of hadronic s...
متن کاملStringing Spins and Spinning Strings
We apply recently developed integrable spin chain and dilatation operator techniques in order to compute the planar one-loop anomalous dimensions for certain operators containing a large number of scalar fields in N = 4 Super Yang-Mills. The first set of operators, belonging to the SO(6) representations [J, L − 2J, J ], interpolate smoothly between the BMN case of two impurities (J = 2) and the...
متن کاملEnergy Spectra of spinning particles around spinning strings in
Riemannian Killing conserved currents are used to find the energy spectra of classical spinning particles moving around a spinning string in Einstein-Cartan (EC) theory of gravity. It is shown that a continuos spectrum is obtained for planar open orbits while a discrete spectrum is obtained for circular planar orbits. A spin-spin effect between the spin of the test particle and the spin of the ...
متن کاملKerr Spinning Particle , Strings , and Superparticle Models
A combined model of the Kerr spinning particle and superparticle is considered. The structure of the Kerr geometry is presented in a complex form as being created by a complex source. A natural supergeneralization of this construction is obtained corresponding to a complex " supersource ". Peforming a supershift to the Kerr and Kerr-Sen solutions we obtain metrics of supergravity black holes wi...
