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(NLO). 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. Talk given at 20th European Conference

Precision calculation for nucleon capture by deuteron with Effective Field Theory
We calculate the cross section for radiative capture of neutron by deuteron
using Effective Field Theory(EFT). The calculation includes
N2LO order and we compare our results with available calculated data below

Logarithmic corrected gravity in the light of Planck 2015
In this letter, we consider the theory of gravity with the lagrangian
density . 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 Einsteins
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
