We present the discovery of four new transiting hot jupiters, detected mainlyfrom SuperWASP-North and SOPHIE observations. These new planets, WASP-52b,WASP-58b, WASP-59b, and WASP-60b, have orbital periods ranging from 1.7 to 7.9days, masses between 0.46 and 0.94 M_Jup, and radii between 0.73 and 1.49R_Jup. Their G1 to K5 dwarf host stars have V magnitudes in the range11.7-13.0. The depths of the transits are between 0.6 and 2.7%, depending onthe target. With their large radii, WASP-52b and 58b are new cases oflow-density, inflated planets, whereas WASP-59b is likely to have a large,dense core. WASP-60 shows shallow transits. In the case of WASP-52 we alsodetected the Rossiter-McLaughlin anomaly via time-resolved spectroscopy of atransit. We measured the sky-projected obliquity lambda = 24 (+17/-9) degrees,indicating that WASP-52b orbits in the same direction as its host star isrotating and that this prograde orbit is slightly misaligned with the stellarequator. These four new planetary systems increase our statistics on hotjupiters, and provide new targets for follow-up studies.
