Application of EFT at Thermal Energies

We have been evaluated some observables of n-d systems by using pionless Effective Field Theory(\EFTNoPion) and insertion of the three-body force up to next-to-next to leading order(N$^2$LO). The evaluated data has been compared with experimental and the three-nucleon calculation of the total cross section with modern realistic two- and three-nucleon forces AV18/UrbIX potential models calculations.Comment: 3 pages, 1 figure and 1 table.

Precision calculation for nucleon capture by deuteron with Effective Field Theory

We calculate the cross section for radiative capture of neutron by deuteron $n+d \to 3H+\gamma$ using Effective Field Theory(EFT). The calculation includes N2LO order and we compare our results with available calculated data below E=0.2 Mev.Comment: 4 pages, 1 eps figures, oral contribution, 19th European Few-Body Conference (fb19), Groningen, Netherlands, August 23 - August 27, 2004.

Logarithmic corrected F(R)F(R) gravity in the light of Planck 2015

In this letter, we consider the theory of $F(R)$ gravity with the lagrangian density $\pounds = R+\alpha R^2 + \beta R^2 \ln \beta R$. We obtain the constant curvature solutions and find the scalar potential of the gravitational field. We also obtain the mass squared of a scalaron in the Einstein$^,$s frame. We find cosmological parameters corresponding to the recent Plank 2015 results. Finally, we analyze the critical points and stability of the new modified theory of gravity and find that logarithmic correction is necessary to have successful model.Comment: arXiv admin note: text overlap with arXiv:1502.00659 by other author
