Testing non-commutative QED $\gamma\gamma\gamma$ and $\gamma\gamma\gamma\gamma$ couplings at LHC [PDF]

The European Physical Journal C, 2004
In this work, we investigate the sensitivity of the process p + p --> q + q --> j + j + gamma + gamma at LHC for the photonic 3- and 4- point functions that appear in non commutative QED. We show that this process serves to study the behavior of the space-space as well as of the space-time non commutativity.

Gamma-Gamma Colliders [PDF]

, 1996
Gamma-gamma colliders make intense beams of gamma rays and have them collide so as to make elementary particles. The authors show, in this article, that constructing a gamma-gamma collider as an add-on to an electron-positron linear collider is possible with present technology and that it does not require much additional cost.

Two-photon widths of the $\chi_{c0, 2}$ states and helicity analysis for $\chi_{c2}\ar\gamma\gamma$} [PDF]

, 2012
Based on a data sample of 106 M $\psi^{\prime}$ events collected with the BESIII detector, the decays $\psi^{\prime}\ar\gamma\chi_{c0, 2}$,$\chi_{c0, 2}\ar\gamma\gamma$ are studied to determine the two-photon widths of the $\chi_{c0, 2}$ states.

EKHARA — new gamma gamma generator [PDF]

Nuclear Physics B - Proceedings Supplements, 2012
The Monte Carlo generator EKHARA allows to simulate the process (e+e- to e+e-pi0) at energies of meson factories. We review the motivation, describe the current status of the generator, and discuss features, which will appear in the forthcoming releases: the two-photon production of eta and eta-prime mesons.

A randomised trial to compare cognitive outcome after gamma knife radiosurgery versus whole brain radiation therapy in patients with multiple brain metastases: research protocol CAR-study B

BMC Cancer, 2018
Background Gamma Knife radiosurgery (GKRS) is increasingly applied in patients with multiple brain metastases and is expected to have less adverse effects in cognitive functioning than whole brain radiation therapy (WBRT).
