On the intrinsic limitation of the Rosenbluth method at large momentum transfer

E. Tomasi-Gustafsson

Correlations in the elastic electron proton scattering data show that the Rosenbluth method is not reliable for the extraction of the electric proton form factors at large momentum…

Search for evidence of two photon contribution in elastic electron proton data

E. Tomasi-Gustafsson, G. I. Gakh

We reanalyze the most recent data on elastic electron proton scattering. We look for a deviation from linearity of the Rosenbluth fit to the differential cross section, which would…

Charm Production in NN and $γ N$ Collisions

Egle Tomasi-Gustafsson

The processes of open and hidden charm production in $N N$ collisions and of open charm production in $γ N$ collisions are studied. The near-threshold cross section is predicted and…

$P$ -parity of charm and strange particles in electroproduction processes, in collinear regime

Michail P. Rekalo, Egle Tomasi-Gustafsson

We show that definite polarization observables for the simplest electroproduction processes, $ℓ + N \to ℓ + B (1/ 2^{\pm}) + M (0^{\pm})$ , $B = Y (Λ, Σ$ or $Y_{c}$ -hyperon, $Θ^{+}$ -pentaquark) an…

Polarization observables in the processes $p + p \to Θ^{+} + Σ^{+}$ and $n + p \to Θ^{+} + Λ^{0}$ , for any spin and parity of the $Θ^{+}$ -hyperon in the threshold region

Michail P. Rekalo, Egle Tomasi-Gustafsson

Using the symmetry properties of the strong interaction, such as the Pauli principle, the P-invariance, the conservation of the total angular momentum and isotopic invariance, we e…

Possible methods for the determination of the $P$ -parity of the $Θ^{+}$ -pentaquark in NN-collisions

Michail P. Rekalo, Egle Tomasi-Gustafsson

We present two possibilities to determine the P-parity of the pentaquark $Θ^{+}$ , in a model independent way, via the measurement of polarization observables in $p + p \to Θ^{+} + Σ^{+}$ , or…
