Tensor coupling and pseudospin symmetry in nuclei
P. Alberto, R. Lisboa, M. Malheiro +1
In this work we study the contribution of the isoscalar tensor coupling to the realization of pseudospin symmetry in nuclei. Using realistic values for the tensor coupling strength…
Perturbative breaking of the pseudospin symmetry in the relativistic harmonic oscillator
R. Lisboa, M. Malheiro, A. S. de Castro +2
We show that relativistic mean fields theories with scalar, , and vector, , quadratic radial potentials can generate a harmonic oscillator with exact pseudospin symmetry {\it…
Charged polytropic compact stars
Subharthi Ray, Manuel Malheiro, Jose' P. S. Lemos +1
In this work, we analyze the effect of charge in compact stars considering the limit of the maximum amount of charge they can hold. We find that the global balance of the forces al…
Compton scattering on the proton, neutron, and deuteron in chiral perturbation theory to O(Q^4)
S. R. Beane, M. Malheiro, J. A. McGovern +2
We study Compton scattering in systems with A=1 and 2 using chiral perturbation theory up to fourth order. For the proton we fit the two undetermined parameters in the O(Q^4) p…
