Abstract: We present a class of exact analytic and static, spherically symmetric blackhole solutions in the semi-classical Einstein equations with Weyl anomaly. Thesolutions have two branches, one is asymptotically flat and the otherasymptotically de Sitter. We study thermodynamic properties of the black holesolutions and find that there exists a logarithmic correction to the well-knownBekenstein-Hawking area entropy. The logarithmic term might come from non-localterms in the effective action of gravity theories. The appearance of thelogarithmic term in the gravity side is quite important in the sense that withthis term one is able to compare black hole entropy up to the subleading order,in the gravity side and in the microscopic statistical interpretation side.
