PAPRICA: The Pair Production Imaging Chamber—Proof of Principle
In Particle Therapy, safety margins are applied around the tumor to account for the beam range uncertainties and ensure an adequate dose coverage of the tumor volume during the therapy.

Scalar leptoquark pair production at hadron colliders [PDF]
We revisit scalar leptoquark pair production at hadron colliders. Apart from QCD contributions, we include the lepton t-channel exchange diagrams relevant in the light of the recent B-flavor anomalies.

Exact WKB analysis of the vacuum pair production by time-dependent electric fields [PDF]
We study the vacuum pair production by a time-dependent strong electric field based on the exact WKB analysis. We identify the generic structure of a Stokes graph for systems with the vacuum pair production and show that the number of produced pairs is ...

Gluino-pair production at the Tevatron [PDF]
The next-to-leading order QCD corrections to the production of gluino pairs at the Tevatron are presented in this paper. Similar to the production of squark-antisquark pairs, the dependence of the cross section on the renormalization/factorization scale is reduced considerably by including the higher-order corrections.

Bulk Density Response and Experimental Study of Pulsed Neutron-Gamma Density Logging
The pulsed neutron-gamma density logging technique is used to measure the bulk density of formations based on the detection of gamma rays from the inelastic scattering of neutrons in the formations.

Lorentz Violation by the Preferred Frame Effects and Cosmic and Gamma Ray Propagation
The ‘relativity with a preferred frame’, designed to reconcile the relativity principle with the existence of the cosmological preferred frame, incorporates the preferred frame at the level of special relativity (SR) while retaining the fundamental ...

Recent high-intensity laser experiments (Cole et al 2018 Phys. Rev. X 8 011020; Poder et al 2018 Phys. Rev. X 8 031004) have shown evidence of strong radiation reaction in the quantum regime. Experimental evidence of quantum effects on radiation reaction

A laser–plasma platform for photon–photon physics: the two photon Breit–Wheeler process
We describe a laser–plasma platform for photon–photon collision experiments to measure fundamental quantum electrodynamic processes. As an example we describe using this platform to attempt to observe the linear Breit–Wheeler process.
