Transmutation of protons in a strong electromagnetic field
Tobias N. Wistisen, Christoph H. Keitel, Antonino Di Piazza
The process of turning a proton into a neutron, positron and electron-neutrino in a strong plane-wave electromagnetic field is studied. This process is forbidden in vacuum and is s…
Numerical approach to the semiclassical method of pair production for arbitrary spins and photon polarization
Tobias N. Wistisen
In this paper we show how to recast the results of the semiclassical method of Baier, Katkov & Strakhovenko for pair production, including the possibility of specifying all the spi…
Testing strong-field QED close to the fully non-perturbative regime using aligned crystals
A. Di Piazza, T. N. Wistisen, M. Tamburini +1
Processes occurring in the strong-field regime of QED are characterized by background electromagnetic fields of the order of the critical field in the rest…
Numerical approach to the semiclassical method of radiation emission for arbitrary electron spin and photon polarization
T. N. Wistisen, A. Di Piazza
We show how the semiclassical formulas for radiation emission of Baier, Katkov and Strakhovenko for arbitrary initial and final spins of the electron and arbitrary polarization of…
Investigation of two photon emission in strong field QED using channeling in a crystal
Tobias N. Wistisen
We investigate the 2nd order process of two photons being emitted by a high-energy electron dressed in the strong background electric field found between the planes in a crystal. T…
Complete treatment of single-photon emission in planar channeling
Tobias N. Wistisen, Antonino Di Piazza
Approximate solutions of the Dirac equation are found for ultrarelativistic particles moving in a periodic potential, which depends only on one coordinate, transverse to the larges…
The Compact Linear ee Collider (CLIC): Physics Potential
P. Roloff, R. Franceschini, U. Schnoor +1
The Compact Linear Collider, CLIC, is a proposed ee collider at the TeV scale whose physics potential ranges from high-precision measurements to extensive direct sensitivit…
The impact of the quantized transverse motion on radiation emission in a Dirac harmonic oscillator
Tobias N. Wistisen, Antonino Di Piazza
We investigate the radiation emitted by an ultrarelativistic electron traveling in a 1-dimensional parabolic potential. Having in mind a simplified model for beamstrahlung, we cons…
Measurement of shower development and its Molière radius with a four-plane LumiCal test set-up
H. Abramowicz, A. Abusleme, K. Afanaciev +57
A prototype of a luminometer, designed for a future e+e- collider detector, and consisting at present of a four-plane module, was tested in the CERN PS accelerator T9 beam. The obj…
Experimental Evidence of Quantum Radiation Reaction in Aligned Crystals
Tobias N. Wistisen, Antonino Di Piazza, Helge V. Knudsen +1
Radiation reaction is the influence of the electromagnetic field emitted by a charged particle on the dynamics of the particle itself. Here we report experimental radiation emissio…
Updated baseline for a staged Compact Linear Collider
The CLIC, CLICdp collaborations, : +515
The Compact Linear Collider (CLIC) is a multi-TeV high-luminosity linear e+e- collider under development. For an optimal exploitation of its physics potential, CLIC is foreseen to…
A method to measure vacuum birefringence at FCC-ee
Ulrik I. Uggerhøj, Tobias N. Wistisen
It is well-known that the Heisenberg-Euler-Schwinger effective Lagrangian predicts that a vacuum with a strong static electromagnetic field turns birefringent. We propose a scheme…
Experimental investigation of the Landau-Pomeranchuk-Migdal effect in low-Z targets
K. K. Andersen, S. L. Andersen, J. Esberg +7
In the CERN NA63 collaboration we have addressed the question of the potential inadequacy of the commonly used Migdal formulation of the Landau-Pomeranchuk-Migdal (LPM) effect by m…
