PROTON INDUCED K + PRODUCTION AND THE ss̄ CONTENT OF THE PROTON ∗
نویسنده
چکیده
We investigate the exclusive proton–induced K production near the kaon threshold. Compared are two models: a meson–exchange model, which includes π, ρ,K andK∗ exchange, together with the dominant baryon resonances, and a quark–gluon model, where momentum sharing is provided via the exchange of two gluons. Based on covariant bound state wave functions for the meson and the baryons — which we treat as quark– diquark objects — first results for the pp → pΛK total cross section are presented for both models.

Polarization Observables in φ Meson Photoproduction and the Strangeness Content of the Proton
The contributions of the diffractive production and direct knockout processes to the φ photoproduction from proton are calculated with the use of Pomeron-photon analogy and a relativistic harmonic oscillator quark model. We find that some of the double polarization observables are very sensitive to a possible ss̄ admixture in the proton. It arises from the different spin structures of the amplit...
متن کاملElectroproduction of φ meson from proton and the strangeness in the nucleon
We analyze the process e p → e p φ near the threshold within uud-ss̄ cluster model as a probe of the strangeness content of proton. Our consideration is based on the relativistic harmonic oscillator quark model which takes into account the Lorentz-contraction effect of the hadron wavefunctions. We find that the knockout mechanisms are comparable to the diffractive production of vector-meson-domi...

In this research, in order to improve our calculations in treatment planning for proton radiotherapy of ocular melanoma, we improved our human eye phantom planning system in GEANT4 toolkit. Different analytical models have investigated the creating of Spread Out Bragg Peak (SOBP) in the tumor area. Bortfeld’s model is one of the most important analytical methods. Using convolution method, a new...
متن کاملAssessment of The Relation Between Energy Of Primary Protons And Undesired Neutron Dose During Proton Therapy By Monte Carlo Method
Introduction: High-energy beams of protons offer significant advantages for the treatment of deepseated local tumors. Their physical depth-dose distribution in tissue is characterized by a small entrance dose and a distinct maximum -Bragg peak- near the end of range with a sharp fall-off at the distal edge. Alongside its advantages there are some point that they need to meticul...
