Small x behavior of parton distributions. A study of higher twist effects

Alexei Yu. Illarionov, Anatoly V. Kotikov, Gonzalo Parente

Higher twist corrections to the structure function F_2 at small x are studied for the case of a flat initial condition for the twist-two QCD evolution in the next-to-leading order…

Time Structure of Muonic Showers

L. Cazon, R. A. Vazquez, A. A. Watson +1

An analytical description of the time structure of the pulses induced by muons in air showers at ground level is deduced assuming the production distance distribution for the muons…

Tests and applications of Migdal's particle path-integral representation for the Dirac Propagator

C. Fosco, J. Sanchez-Guillen, R. A. Vazquez

We derive some non-perturbative results in 1+1 and 2+1 dimensions within the context of the particle path-integral representation for a Dirac field propagator in the presence of an…

Fission-Residues Produced in the Spallation Reaction 238U+p at 1 A GeV

M. Bernas, P. Armbruster, J. Benlliure +16

Fission fragments from 1 A GeV 238U projectiles irradiating a hydrogen target were investigated by using the fragment separator FRS for magnetic selection of reaction products incl…

The Effect of Non Gaussian Errors on the Determination of Steeply Falling Spectra

C. O. Escobar, L. G. dos Santos, R. A. Vazquez

The determination of a steeply falling energy spectrum from rare events with non-gaussian measurement errors is a delicate matter. The final shape of the spectrum may be severely d…
