Cross section of pseudoscalar meson photoproduction within the ELA
(Elsevier Science, 2015-03)
We study the contributions of background and resonance terms to the total cross section of photoproduction of mesons off the free nucleon. The model we use is consistent and based on an effective Lagrangian approach (ELA) ...
Photoproduction total cross section and shower development
(American Physical Society, 2015-12)
The total photoproduction cross section at ultrahigh energies is obtained using a model based on QCD minijets and soft-gluon resummation and the ansatz that infrared gluons limit the rise of total cross sections. This cross ...
The nuclear matter effects in π0 photoproduction at high energies
The in-medium influence on π0 photoproduction from spin zero nuclei is carefully studied in the GeV range using a straightforward Monte Carlo analysis. The calculation takes into account the relativistic nuclear recoil for ...
Different vertex parameterizations and propagators for the Δ contribution in π-photoproduction
(IOP Publishing, 2017-03)
We evaluate the total cross section for the π-photoproduction process and analyze the behavior of the Δ(1232) resonance contribution when the photon energy is increased from threshold up to 0.7 GeV. Within this energy range ...

Forward-angle incoherent photoproduction of pseudoscalar mesons off nuclei
(AMER PHYSICAL SOCCOLLEGE PK, 2012)
The mechanism of forward angle incoherent photoproduction of pseudoscalar mesons off nuclei is revisited via the time-dependent multicollisional Monte Carlo (MCMC) intranuclear cascade model. Our results-combined with ...
Nuclear photoproduction of pseudoscalar mesons at forward angles up to 6.0 GeV
The nuclear incoherent π 0 photoproduction cross section from 12C is evaluated at forward angles in the 4.0 to 6.0 GeV energy range using the multicollisional intranuclear cascade model MCMC. The model incorporates some ...
Photoinactivation of tyrosinase sensitized by folic acid photoproducts
(Elsevier Science Sa, 2015-08)
Tyrosinase catalyzes in mammals the first and rate-limiting step in the biosynthesis of the melanin, the main pigment of the skin. Pterins, heterocyclic compounds able to photoinduce oxidation of biomolecules, accumulate ...
