Gamma or no gamma, that is the question

Trends in Cognitive Sciences, 2014
Numerous studies suggest that gamma-band synchronization is central to visual processing, yet most of them have used artificial stimuli. A new study using electrocorticography (ECoG) in humans reported finding no gamma for many natural images and for visual noise.

The C coefficients of the amplitudes of Z to 3 gamma and gamma gamma to gamma gamma*

Journal of Physics G: Nuclear and Particle Physics, 1993
The contributions of the W loops to the decay of the Z into three photons and to the scattering of light by light are calculated. The C coefficients of the amplitudes of Z to 3 gamma and gamma gamma to gamma gamma* are shown. They are very useful for checking the authors earlier results.

Gamma and gamma-coupled beams

Applied Optics, 2018
A new class of scalar, rotationally symmetric Gaussian-like beams is introduced. The slowly varying amplitudes of such beams are represented as analytical solutions to the paraxial wave equation, described in terms of the incomplete gamma functions and their products with quadratic exponential and power functions of different kinds.

Formation of the pseudoscalars pi 0, eta, and eta ' in the reaction gamma gamma --> gamma gamma.

Physical review. D, Particles and fields, 1988
The Crystal Ball detector has been used at the DORIS II storage ring at DESY to study the reaction e+ e- -> e+ e- gamma* gamma* -> e+ e- X -> e+ e- gamma gamma, where X is a narrow resonance with mass between 100 and 3000 MeV. Formation of pi0, eta and eta' mesons is observed, and the following meson partial widths are obtained: Gamma(pi0 -> gamma ...
