BENEDETTI, V.  e  CASINI, H.. Entanglement entropy for spin 2 field on a shpere. An. AFA [online]. 2020, vol.31, n.2, pp.71-76. ISSN 0327-358X.

In this paper we compute the entanglement entropy for linearized gravitons (as helicity 2 particles) on a sphere defined over a Minkowski background. Previously, we analyse the cases of the solar and vector fields by decomposition in spherical harmonics. Then we generalise this method for the tensor field. We obtain the universal logarithmic coefficient and we analyse its relation to the conformal anomaly.

Palavras-chave : entanglement entropy; spin; sphere.
