Extra Dimensions in the Early Universe
Douglas J. Buettner, P. D. Morley, Ivan Schmidt
We investigate the possible occurrence of extra spatial dimensions (D = 3+epsilon) in the early universe. A detailed calculation is presented which shows that the crucial signal is…
CP-violation in high-energy collisions of polarized protons
Sergey Kovalenko, Ivan Schmidt, Jacques Soffer
We study the possibility of a large CP/T-violation in lepton pair production in the collisions of polarized protons at RHIC-BNL. We propose the single transverse spin asymmetry whi…
From Screening to Confinement in a Gauge-Invariant Formalism
Patricio Gaete, Iván Schmidt
Features of screening and confinement are reviewed in two-dimensional quantum electrodynamics (QED2). Our discussion is carried out using the gauge-invariant but path-dependent var…
Flavor and Spin Structure of Octet Baryons at Large x
Bo-Qiang Ma, Ivan Schmidt, Jian-Jun Yang
The quark flavor and spin distributions in octet baryons are calculated both in the SU(6) quark spectator diquark model and in a perturbative QCD (pQCD) based model. It is shown th…
Quark Structure of from -Polarization in Z Decays
Bo-Qiang Ma, Ivan Schmidt, Jian-Jun Yang
The flavor and spin structure for the quark distributions of the -baryon is studied in a perturbative QCD (pQCD) analysis and in the SU(6) quark-diquark model, and then applied…
Peripheral Meson Model of Deep Inelastic Rapidity Gap Events
Hung-Jung Lu, Rodrigo Rivera, Ivan Schmidt
We show that a peripheral meson model can explain the large deep inelastic electron-proton scattering rapidity gap events observed at HERA.
