Perturbative fragmentation

B. Z. Kopeliovich, H. -J. Pirner, I. K. Potashnikova +2

The Berger model of perturbative fragmentation of quarks to pions is improved by providing an absolute normalization and keeping all terms in a (1-z) expansion, which makes the cal…

Spin observables of the reaction pd-3He eta and quasi-bound 3He-eta pole

Yu. N. Uzikov

A formalism for spin observables of the reaction is derived in a model independent way. The general case with a full set of six independent spin amplitudes is studie…

Conformal Invariance in the Leigh-Strassler deformed N=4 SYM Theory

L. V. Bork, D. I. Kazakov, G. S. Vartanov +1

We consider a full Leigh-Strassler deformation of the SYM theory and look for conditions under which the theory would be conformally invariant and finite. Applying the…

Source breakup dynamics in Au+Au Collisions at sqrt(s_NN)=200 GeV via three-dimensional two-pion source imaging

PHENIX Collaboration, S. Afanasiev

A three-dimensional (3D) correlation function obtained from mid-rapidity, low pT pion pairs in central Au+Au collisions at sqrt(s_NN)=200 GeV is studied. The extracted model-indepe…

Single- and Double-Pion Production in Nucleon Collisions on the Nucleon and on Nuclei -- the ABC Effect and its Possible Origin in a Dibaryonic Resonance

H. Clement, M. Bashkanov, E. Doroshkevich +5

The ABC effect -- an intriguing low-mass enhancement in the invariant mass spectrum -- is known from inclusive measurements of two-pion production in nuclear fusion reactions.…

Surface modes and photonic modes in Casimir calculations for a compact cylinder

V. V. Nesterenko

A rigorous formulation of the problem of calculating the electromagnetic vacuum energy of an infinite dielectric cylinder is discussed. It is shown that the physically relevant spe…
