Sinha, KP and Srivastava, SK (1995) Dual nature of Ricci scalar and creation of spinless particles. In: Pramana, Journal of Physics, 44 (4). pp. 333-345.
Manifestation of a Ricci scalar like a matter field as well as a geometrical field, at high energy, has been noted earlier. Here, its interaction with another scalar field is considered in four-dimensional curved space-time. This interaction leads to the production of a large number of pairs of spinless particle-antiparticles due to expansion of the early universe in the vacuum state (provided by the temperature dependent Coleman-Weinberg like potential for the Ricci field), where spontaneous symmetry breaking takes place.
