gamma p and gamma gamma scattering from (p)over-bar-p, pp forward amplitudes in a QCD eikonal model with a dynamical gluon mass
(American Physical Soc, 2006-04-01)
We examine the gamma p photoproduction and the hadronic gamma gamma total cross sections by means of a QCD eikonal model with a dynamical infrared mass scale. In this model, where the dynamical gluon mass is the natural ...
Microquasars and Gamma-ray Sources
(Science Press, 2005-12)
Microquasars are X-ray binary systems with non-thermal radio emission originated in jet-like features. They are attractive sites for gamma-ray production, since relativistic particles in the jet should traverse locally ...
Prediction of h -> gamma Z from h -> gamma gamma at the LHC for the IMDS3 model
(Iop Publishing Ltd, 2015-11-01)
We consider the decays h -> gamma gamma, gamma Z in the context of an extension of the Standard Model with two inert doublets and an additional S-3 symmetry. This model contributes to for these processes through new charged ...

Probing Higgs couplings in e(+)e(-)->gamma gamma gamma
(Elsevier B.V., 1996-12-05)
We investigate the existence of anomalous Higgs boson couplings, H gamma gamma and HZ gamma, through the analysis of the process e(+)e(-) gamma gamma gamma at LEP2 energies. We suggest some kinematical cuts to improve the ...

Influence of Fc gamma RIIIb polymorphism on its ability to cooperate with Fc gamma RIIa and CR3 in mediating the oxidative burst of human neutrophils
(Elsevier B.V., 2014-08-01)
Considering that human neutrophil Fc gamma RIIa and Fc gamma RIIIb receptors interact synergistically with CR3 in triggering neutrophil functional responses, allelic polymorphisms in these receptors might influence such ...
On high Q(2) behavior of the pion form factor for transitions gamma*gamma -> pi(0) and gamma*gamma* -> pi(0) within the nonlocal quark-pion model
(Elsevier B.V., 2000-03-02)
The behavior of the transition pion form factor for processes gamma (*)gamma --> pi(0) and gamma (*)gamma (*) --> pi(0) at large values of space-like photon momenta is estimated within the nonlocal covariant quark-pion ...
An upper limit on the cosmic-ray luminosity of individual sources from gamma-ray observations
(Institute of Physics - IOPBristol, 2013-12)
Different types of extragalactic objects are known to produce TeV gamma-rays. Some of these objects are the most probable candidates to accelerate cosmic rays up to '10 POT.20' eV. It is very well known that gamma-rays can ...
New Higgs interactions in ZZ gamma and Z gamma gamma production
(Elsevier B.V., 1998-01-08)
The effect of new operators that only modify the bosonic couplings of the Higgs boson, without altering the WW gamma or WWZ three-point functions, are examined in the e(+)e(-) --> ZZ gamma and Z gamma gamma processes. We ...
