Loop quantum gravity and cosmological constant

An one-parameter regularization freedom of the Hamiltonian constraint for loop quantum gravity is analyzed. The corresponding spatially flat, homogenous and isotropic model includes two well-known models cosmology as special cases. bounce nature tenable in generalized For positive value parameter, effective leads to an asymptotic de-Sitter branch Universe connecting standard Friedmann by bounce. Remarkably, suitably choosing observational cosmological constant can emerge at large volume limit from effect gravity, Newtonian satisfies experimental restrictions meantime.
