Analysing powers for the reaction and for np elastic scattering from 270 to 570 MeV

M. Daum, M. Finger, M. Finger +10

The analysing power of the reaction for neutron energies between threshold and 570 MeV has been determined using a transversely polarised…

Search for Leptoquarks in Electron-Photon Scattering at sqrt(s_ee) up to 209 GeV at LEP

The OPAL collaboration, G. Abbiendi

Searches for first generation scalar and vector leptoquarks, and for squarks in R-parity violating SUSY models with the direct decay of the squark into Standard Model particles, ha…

Quantum effects in a rotating spacetime

Eugen Radu, Dumitru Astefanesei

The behavior of a arbitrary coupled quantum scalar field is studied in the background of the Gödel spacetime. Closed forms are derived for the effective action and the vacuum expec…

Integrals of monomials over the orthogonal group

Thomas Gorin

A recursion formula is derived which allows to evaluate invariant integrals over the orthogonal group O(N), where the integrand is an arbitrary finite monomial in the matrix elemen…

A random matrix approach to decoherence

Thomas Gorin, Thomas H. Seligman

In order to analyze the effect of chaos or order on the rate of decoherence in a subsystem, we aim to distinguish effects of the two types of dynamics by choosing initial states as…

Single-spin azimuthal asymmetry in exclusive electroproduction of pi^+ mesons

HERMES Collaboration, A. Airapetian

A single-spin asymmetry in the distribution of exclusively produced pi^+ mesons azimuthally around the virtual photon direction relative to the lepton scattering plane has been mea…
