Proton structure function. Soft and hard Pomerons

P. Desgrolard, E. Martynov

Regge models for proton structure function with and without a hard Pomeron contribution are compared with all available data in the region $W > 3$ GeV, $Q^{2} \leq 3000$ GeV $^{2}$ and…

Approximate solution of the BFKL equation applicable at HERA

P. Desgrolard, L. Jenkovszky, F. Paccanoni

We suggest a formula interpolating between the known asymptotic regimes of the BFKL equation as the approximate solution of that equation. The parameters appearing in this interpol…

Of dips and structures

P. Desgrolard, M. Giffon, E. Martynov +1

A detailed analysis of the existence of high energy secondary diffractive dips and structures in the extrapolations of the fits to the data is given. The existence of these dips an…

The proton structure function and a soft Regge Dipole Pomeron: a test with recent data

P. Desgrolard, A. Lengyel, E. Martynov

A recently published soft Regge Dipole Pomeron model intended for all $x$ and $Q^{2}$ is proved to give a good agreement with (non fitted) recent HERA data from ZEUS (SVX95) on the p…

Local nuclear slope and curvature in high energy $pp$ and $p ˉ p$ elastic scattering

P. Desgrolard, J. Kontros, A. I Lengyel +1

The local nuclear slope $B (s, t) = \frac{d}{d t} (ln \frac{d σ _{n} ( s , t )}{d t})$ is reconstructed from the experimental angular distributions with a procedure that uses overlapping $t$ -…
