Resumen:
We study the combined effects of a finite volume and an external
magnetic field on the charged two-pion correlation function. For these
purposes, we consider a dilute system of pions where the finite volume
effects are introduced computing the pion wave functions with rigid
boundary conditions in a cylindrical geometry in the presence of a
uniform and constant magnetic field. We find that for slow pions,
namely, for the case where the average pair momentum is small, the
correlation function shows a large distortion, as opposed to the case
where the average pair momentum is large. For a finite density system,
the intercept of the correlation function is reduced, signaling the
increasing importance of the pion ground state contribution. An
increasing strength of the magnetic field reduces the importance of the
ground state and the intercept becomes closer to 2.
