“…10 Impressive constraints on SME coefficients from many experiments have been obtained. 1 The generality of the SME framework insures these constraints apply to any specific Lorentz-violating model that is consistent with realistic effective field theory.…”

“…Motivated by the prospect of minuscule observable effects arising from Planck-scale physics, searches for Lorentz and CPT violation have made impressive advances in recent years. 1 The scope of ongoing efforts presented at the CPT'19 meeting indicates that this rapid pace of development will continue unabated, with experiments achieving sensitivities to Lorentz violation that are orders of magnitude beyond present capabilities and providing unprecedented probes of the CPT theorem. Substantial theoretical advances in the subject are also being made, and the prospects are excellent for completing a comprehensive description of possible effects on all forces and particles and for achieving a broad understanding of the underlying mathematical structure in the near future.…”

In this paper we consider some physical phenomena in the vicinity of a conducting plate in a non-minimal Lorentz-violating scenario in 3+1 dimensions. We consider a model where the dynamics of the abelian gauge field is given by the standard Maxwell Lagrangian added by a Lorentz symmetry breaking term with the presence of higher order derivatives in the gauge field. The Lorentz symmetry breaking is due to the presence of a single background vector d λ and we perform the calculations perturbatively up to first order in d λ. We obtain the propagator for the gauge field in the presence of a mirror and the interaction force between the mirror and a point-like electric charge, as well as the interaction force between the mirror and an electric dipole. We show that, on the contrary to what happens in a minimal Lorentz-violating scenario with one single background field (L.H.C. Borges, F.A. Barone, Eur. Phys. J. C 693, 77, 2017), the image method is not valid in the model that we consider in this paper. As a consequence, the symmetry of spatial reflection on the mirror is broken. We also investigate the emergence of a torque in a system composed by a mirror and a point-like electric charge, placed at a fixed distance apart each other. The results obtained in this work have no counterpart in the Maxwell electrodynamics and were not verified in any Lorentz-violating scenario previously.

“…These include activities focusing on the gravitational behaviour of antimatter. No compelling theoretical argument seems to support that a difference between the gravitational behaviour of matter and antimatter should be expected [1], although some attempts have been made to show the contrary [2][3][4][5] and it would be allowed in the context of the Standard Model Extension (SME) [6,7]. Moreover, observations and experiments have been interpreted as evidence against the existence of antigravity type forces [8][9][10][11].…”

Proposal for enhancement of antihydrogen ion production in the GBAR experiment

The production of antihydrogen ions (H̅+) in the GBAR experiment will occur via a two step charge exchange process. In a first reaction, the antiprotons(P̅) from the ELENA ring will capture a positron from a positronium(Ps) target producing antihydrogen (H̅) atoms. Those interacting in the same Ps target will produce in a second step H̅+. This results in a dependence for the H̅+ production rate which is roughly proportional to the Ps density squared. Wepresent a scheme to increase the anti-ion production rate in the GBAR experiment by tailoring the antiproton to the positron pulse in order to maximise thetemporal overlap of Ps and p̅. Detailed simulations show that an order of magnitude could be gained by bunching the antiprotons from ELENA. In order to avoid losses in their capture in the Paul trap due to the energy spread introducedby the bunching, debunching with a symmetrical inverted pulse can be appliedto the H̅+ ions.
