Dual nature of Ricci scalar and creation of spinless particles
نویسنده
چکیده
Abstract. Manifestation of Ricci scalar like a matter field as well as a geometrical field, at high energy, has been noted earlier [9], 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-antiparticle due to expansion of the early universe in the vacuum state (provided by temperature dependent Coleman-Weinberg like potential for Ricci field), where spontaneous symmetry breaking takes place.

DUAL NATURE OF THE RICCI SCALAR, CREATION OF SPINLESS AND SPIN - 1/2 PARTICLES AS WELL AS A NEW COSMOLOGICAL SCENARIO I S.K.Srivastava,
In earlier papers [11-17], it is found that the Ricci scalar behaves in a dual manner (i) like a matter field and (ii) like a geometrical field. In ref.[17], inhomogeneous cosmological models are derived using dual roles of the Ricci scalar. The essential features of these models is capability of these to exhibit gravitational effect of compact objects also in an expanding universe. Here, produ...
متن کاملDual Nature of the Ricci Scalar and Its Certain Consequences
Ricci scalar is the key ingredient of non-Newtonian theory of gravity, where space-time geometry has a crucial role. Normally, it is supposed to be a geometrical field, but interestingly it also behaves like a physical field. Thus it plays dual role in the arena of gravitation. This article is an overview of the work related to dual roles of the Ricci scalar. A scalar is a mathematical concept ...
متن کاملSinglet scalar dark matter in noncommutative space
In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered, but our information about the nature of dark matter is still limited. There are such particle candidates as scalar matetr, fermion, boson, gauge boson, etc.; however, they have nei...
متن کاملEvolution of the first eigenvalue of buckling problem on Riemannian manifold under Ricci flow
Among the eigenvalue problems of the Laplacian, the biharmonic operator eigenvalue problems are interesting projects because these problems root in physics and geometric analysis. The buckling problem is one of the most important problems in physics, and many studies have been done by the researchers about the solution and the estimate of its eigenvalue. In this paper, first, we obtain the evol...
متن کاملSpinless Matter in Transposed-Equi-Affine Theory of Gravity
We derive and discus the equations of motion for spinless matter: relativistic spinless scalar fields, particles and fluids in the recently proposed by A. Saa model of gravity with covariantly constant volume with respect to the transposed connection in Einstein-Cartan spaces. A new interpretation of this theory as a theory with variable Plank ”constant” is suggested.
