OBJECTIVE
Pertussis persists in the United States despite high immunization rates. This report characterizes the presentation and acute course of critical pertussis by quantifying demographic data,â€¦ (More)

Demanding the analyticity of hadronic observables (calculated in terms of power series of the running coupling) as a whole, we show that they are free of the Landau singularity. Employing resummationâ€¦ (More)

Worldline techniques are employed to study the general behaviour of the fermionfermion collision amplitude at very high energies in a non-abelian gauge field theory for the forward and fixed angleâ€¦ (More)

A theoretical scheme which relates multiparticle states generated in ultrarelativistic nuclear collisions to a QCD phase transition is considered in the framework of the uni-versality class providedâ€¦ (More)

We employ the Polyakov world-line path-integral version of QCD to identify and resum at leading perturbative order enhanced radiative gluon contributions to the Drell-Yan type (qqÌ„ pair annihilation)â€¦ (More)

Perturbative Computation of the Gluonic Effective Action via Polyakov â€™ s World-Line Path Integral

The Polyakov world-line path integral describing the propagation of gluon field quanta is constructed by employing the background gauge fixing method and is subsequently applied to analyticallyâ€¦ (More)

Employing the Worldline casting of the Dosch-Simonov Stochastic Vacuum Model (SVM) for QCD, a simulated meson-meson scattering problem is studied in the Regge kinematical regime. The process isâ€¦ (More)

An effective field theoretic description of the Isgur-Wise function in heavy-meson transitions is presented which emulates soft interactions by a fermion worldline with an infinitesimalâ€¦ (More)

The spin-field interaction is considered, in the context of the gauge fields/string correspondence, in the large â€™t Hooft coupling limit. The latter can be viewed as a WKB-type approximation to theâ€¦ (More)

We calculate Sudakov-type form factors for isolated spin-1/2 particles (fermions) entering non-Abelian gauge-field systems. We consider both the onand the off-mass-shell case using a methodologyâ€¦ (More)
