Polarization Phenomena in Small-Angle Photoproduction of ee Pairs and the Gerasimov–Drell–Hearn Sum Rule

Photoproduction of e+e− pairs at small angles is investigated as a tool to determine the functions f1 and f2 entering the real-photon forward Compton scattering amplitude. The method is based on an interference of the Bethe–Heitler and the virtual Compton scattering mechanisms, generating an azimuthal asymmetry in the e+ versus e yield. The general case of a circularly polarized beam and a long...

Spin Polarization Phenomena in Dense Nuclear Matter

Spin polarized states in nuclear matter with an effective nucleon-nucleon interaction are studied for a wide range of isospin asymmetries and densities. Based on a Fermi liquid theory, it is shown that there are a few possible scenarios of spin ordered phase transitions: (a) nuclear matter undergoes at some critical density a phase transition to a spin polarized state with the oppositely direct...

Gluon Polarization in ee → tt̄G: Polar Angle Dependence and Beam Polarization Effects

We calculate the linear and circular polarization of gluons produced in conjunction with massive quarks in the annihilation process e+e− → qq̄G. The linear polarization is calculated in the hadron event plane as well as in the gluon-beam plane. Beam polarization and polar orientation effects are included in our discussion. For typical top pair production energies at the Next-Linear-Collider (NLC...

Psychoanalytic process and interactive phenomena.

Psychoanalytic process is defined as the interaction between the psychoanalyst and the patient, primarily through the interplay of transference and resistance. Transference and resistance are understood as a unitary phenomenon that can be expressed either as an intrapsychic potential or as an interpersonal relationship. One of the aims of psychoanalytic technique is to encourage, through interp...
