We study the fragmentation of a transversely polarized quark into a non collinear (k⊥ 6= 0) spinless hadron and the fragmentation of an unpolarized quark into a non collinear transversely polarized spin 1/2 baryon. These nonperturbative properties are described by spin and k⊥ dependent fragmentation functions and are revealed in the observation of single spin asymmetries. Recent data on the pro...

The twist-four quark and gluon distributions in a transversely polarized nucleon are identified and relations among them are discussed by using QCD equations of motion. Their contribution, at the order of O ( 1/Q ) , to the Drell-Yan cross section in transversely polarized nucleon-nucleon collisions is calculated. Submitted to: Phys. Rev.

We consider a rescattering mechanism to calculate a leading twist T -odd pion fragmentation function, a candidate for filtering the transversity properties of the nucleon. We evaluate the single spin azimuthal asymmetry for a transversely polarized target in semi-inclusive deep inelastic scattering (for HERMES kinematics) and the double T -odd cos2φ asymmetry in this framework. Introduction The...

Crystals are seen occasionally within the diameter of transversely sectioned collagen fibrils near the calcification front of newly formed bone.

Laterally periodic resonators, which can be constructed by use of transversely periodic phase- or amplitude-modulating elements in a cavity, are proposed for stabilization and generation of transversely coherent output from large-area gain. Lasers with periodic resonators have the combined features of conventional cavities and laser arrays. Significant low-order transverse modes and mode discri...
