Popis: A four-dimensional solution of the classical equation of motion in the low-energy effective field theory for heterotic string theory is chosen. Popularly, this is known as Kerr–Sen black hole. Thermodynamic picture for this particular black hole is constructed. Applying the generalized uncertainty principle (GUP), the first-order correction of it in connection with the thermal heat capacity (THC) and due to conformal field theory (CFT) background are studied. All the cases are pointing towards an unstable thermodynamic phase of the concerned black holes. Phase transitions are located by studying where signs of the heat capacity are changing. Unlike the black holes embedded in AdS space, first-order corrected entropy is found to be unphysical. Photons by tunneling rate are calculated. A comparative study of the effect of generalized uncertainty principle parameter [Formula: see text] along with the black holes’ parameters on the thermodynamics of the black hole is presented.
