Some consequences of theories with maximal acceleration in laser-plasma acceleration

TL;DR

This paper explores how theories with a maximal acceleration influence laser-plasma acceleration, showing that certain predictions are testable and can set bounds on theoretical parameters like the Born-Infeld constant.

Contribution

It demonstrates that a higher order jet theory predicts damping of maximal acceleration in large charge bunches, and uses laser-plasma data to constrain Born-Infeld theory parameters.

Findings

Maximal acceleration is damped for large charge bunches in jet theory.

Laser-plasma acceleration can set upper bounds on Born-Infeld parameter b.

Predictions of the theories are falsifiable with improved beam qualities.

Abstract

In this paper we consider classical electrodynamic theories with maximal acceleration and some of their phenomenological consequences for laser-plasma acceleration. It is shown that in a recently proposed higher order jet theory of electrodynamics, the maximal effective acceleration reachable by a consistent bunch of point charged particles being accelerated by the wakefield is damped for bunches containing large number of charged particles. We argue that such prediction of the theory is falsifiable. In the case of Born-Infeld kinematics, laser-plasma acceleration phenomenology provides an upper bound for the Born-Infeld parameter $b$. Improvements in the beam qualities will imply stronger constraints on $b$.
