    "abstract": "The definition of mass of a scalar field in a curved space has often been\ngeneralized by grouping coupling terms between the field and the Ricci\ncurvature with non-curvature-related mass terms. In a broader point of view,\none sees that a common misunderstanding resulting from such an identification\nleads one, in the case of the spin 2 field, to regard the cosmological constant\nas a non-vanishing mass of cosmological origin for the graviton. Similarly,\nthere are inconsistencies for the spin 1 field. Instead, the intrinsic mass of\na field should be regarded as being independent of the background curvature.",
