Title: A survey for lensed Lyman break galaxies

Abstract: Research on high redshift (z > 2) galaxies has now started moving beyond ensemble statistical studies and into detailed physical analyses of galaxy properties. These include recent attempts at high-S/N, high resolution optical and infrared spectroscopy (e.g., Pettini et al.\ 1998, 2000; Teplitz et al. 2000) and sub-mm observations (Chapman et al. 2000). These, however, are limited by the faintness of most Lyman break selected galaxies - only gravitationally lensed examples are bright enough for detailed spectroscopic study, and only two such lensed objects are known at z ~ 3. Here we propose to continue our ``snapshot'' survey for Lyman break galaxies lensed by massive foreground galaxy clusters. These will be ideal targets for measuring stellar population properties, metallicities, and kinematics with 8-10m spectroscopy, and dust content with SCUBA.
