String Model for Analytic Nonlinear Regge Trajectories
نویسنده
چکیده
We present a new generalized string model for Regge trajectories J = J(E2), where J and E are the orbital momentum and energy of the string, respectively. We demonstrate that this model is not to produce linear Regge trajectories, in contrast to the standard Nambu-Goto string, but generally nonlinear trajectories, which in many cases can be given in analytic form. As an example, we show how the model generates square-root, logarithmic and hyperbolic trajectories that have been discussed in the literature.

The glueball Regge trajectory from the string - inspired theory
The special case of 4D string-like theory proposed early is investigated. Regge trajectories in the developed model are non-linear for the small masses and the values of spin and have the different asymptotical slopes αp. The value αp just as the form of the trajectory depends from the quantum state of some ”internal“ (relativistic invariant) variables. It is also shown that some trajectories h...
متن کاملAnalytic model of a Regge trajectory in the space-like and time-like regions
A model for a Regge trajectory compatible with the threshold behavior required by unitarity and asymptotics in agreement with Mandelstam analyticity is analyzed and confronted with the experimental data on the spectrum of the ρ trajectory as well as those on the πp → π0n charge-exchange reaction. The fitted trajectory deviates considerably from a linear one both in the space-like and time-like ...
متن کاملRegularities in hadron systematics, Regge trajectories and a string quark model
An empirical principle for the construction of a linear relationship between the total angular momentum and squared-mass of baryons is proposed. In order to examine linearity of the trajectories, a rigorous least-squares regression analysis was performed. Unlike the standard Regge-Chew-Frautschi approach, the constructed trajectories do not have non-linear behaviour. A similar regularity may ex...
متن کاملEffective String Theory of Vortices and Regge Trajectories of Hybrid Mesons with Zero Mass Quarks
We show how a field theory containing classical vortex solutions can be expressed as an effective string theory of long distance QCD describing the two transverse oscillations of the string. We use the semiclassical expansion of this effective string theory about a classical rotating string solution to obtain Regge trajectories for mesons with zero mass quarks. The first semiclassical correctio...
متن کاملString Models of Glueball and Regge Trajectories
The closed relativistic string carrying two point-like masses is considered as the model of a glueball with two constituent gluons. Here the gluon-gluon interaction is simulated by a pair of strings. For this system exact solutions of classical equations of motions are obtained. They describe rotational states of the string resulting in the set of quasilinear Regge trajectories with different b...
