Title Signatures of excited monopolium Type Journal Article
Year 2022 Publication European Physical Journal Plus Abbreviated Journal Eur. Phys. J. Plus
Volume 137 Issue 12 Pages 1316 - 19pp
Keywords
Abstract We study electromagnetic properties of particles with magnetic moment and no charge using their behavior when traversing coils and solenoids. These particles via the Faraday-Lenz law create a current whose energy we calculate. We analyze both the case of very long lived, almost stable, particles and those with a finite lifetime. We use this development to study the behavior of monopolium a monopole-antimonopole bound state in its excited states.

Title Hybrid PET/Compton-camera imaging: an imager for the next generation Type Journal Article
Year 2023 Publication European Physical Journal Plus Abbreviated Journal Eur. Phys. J. Plus
Volume 138 Issue 3 Pages 214 - 19pp
Keywords
Abstract Compton cameras can offer advantages over gamma cameras for some applications, since they are well suited for multitracer imaging and for imaging high-energy radiotracers, such as those employed in radionuclide therapy. While in conventional clinical settings state-of-the-art Compton cameras cannot compete with well-established methods such as PET and SPECT, there are specific scenarios in which they can constitute an advantageous alternative. The combination of PET and Compton imaging can benefit from the improved resolution and sensitivity of current PET technology and, at the same time, overcome PET limitations in the use of multiple radiotracers. Such a system can provide simultaneous assessment of different radiotracers under identical conditions and reduce errors associated with physical factors that can change between acquisitions. Advances are being made both in instrumentation developments combining PET and Compton cameras for multimodal or three-gamma imaging systems, and in image reconstruction, addressing the challenges imposed by the combination of the two modalities or the new techniques. This review article summarizes the advances made in Compton cameras for medical imaging and their combination with PET.

Title Bulk fields localization on thick string-like brane in f(T) gravity Type Journal Article
Year 2023 Publication European Physical Journal Plus Abbreviated Journal Eur. Phys. J. Plus
Volume 138 Issue 8 Pages 730 - 15pp
Keywords
Abstract This paper aims to investigate the influence of torsion on bulk fields in the codimension two thick brane in f(T) modified teleparallel gravity. It is shown that the brane supports the localization of gauge field zero mode without an extra coupling. However, Kalb-Ramond and fermionic fields require a suitable coupling. Then, it is proposed a geometrical coupling based on results in 5D thick brane in modified teleparallel gravities. The Kalb-Ramond field is coupled to torsion scalar T through a gauge-invariant interaction. For the case of fermionic fields, we study the Dirac fermions and gravitino with a derivative geometrical coupling. For all of the fields, it obtained massive and resonant modes by employing the Schodinger-like approach.

Title Casimir effect in a Lorentz-violating tensor extension of a scalar field theory Type Journal Article
Year 2024 Publication European Physical Journal Plus Abbreviated Journal Eur. Phys. J. Plus
Volume 139 Issue 2 Pages 165 - 12pp
Keywords
Abstract This paper investigates the Casimir energy modifications due to the Lorentz-violating CPT-even contribution in an extension of the scalar QED. We have considered the complex scalar field satisfying Dirichlet boundary conditions between two parallel plates separated by a small distance. An appropriate tensor parametrization allowed us to study the Casimir effect in three different configurations: isotropic, anisotropic parity-odd, and anisotropic parity-even. We have shown that the Lorentz-violating contributions can promote either an increase or a decrease in the Casimir energy evaluated in the isotropic configuration, depending on whether the violation parameters are taking as positive or negative values. On the other hand, for the anisotropic parity-even case the Casimir energy only decreases, while for the anisotropic parity-odd cases it only increases. Therefore, from these last two results it seems that the Casimir energy is sensitive to the parity of Lorentz-violating coefficients.

Title Energy loss of monopolium in a medium Type Journal Article
Year 2023 Publication European Physical Journal Plus Abbreviated Journal Eur. Phys. J. Plus
Volume 138 Issue 9 Pages 850 - 11pp
Keywords
Abstract We study the energy loss of excited monopolium in an atomic medium. We perform a classical calculation in line with a similar calculation performed for charged particles which leads in the non-relativistic limit to the Bethe-Bloch formula except for the density dependence of the medium, which we do not consider in this paper. Our result shows that for maximally deformed Rydberg states, the ionization of monopolium in a light atomic medium is similar to that of light ions.
