Lepton Photon 2011 XXV INTERNATIONAL SYMPOSIUM ON LEPTON PHOTON INTERACTIONS AT HIGH ENERGIES August 22-27, 2011 Webpage: http://www.tifr.res.in/~lp11 Tata Institute of Fundamental Research, Mumbai, India *First Bulletin* The XXV International Symposium on Lepton Photon Interactions at High Energies will be held at the Tata Institute of Fundamental Research, Mumbai, India during August 22-27, 2011. Please mark your calenders. This Symposium follows the tradition of a long series of high energy physics conferences, the International Symposia on Lepton and Photon Interactions at High Energies. The programme will feature plenary reports covering topics of major interest to the particle physics community. A poster session will be organised where students and young post-docs can present their work. Unlike past Lepton Photon symposia, there will be no country-wise quota of delegates for this symposium. If you need an invitation letter for attending the symposium, then please fill up the invitation request form from the symposium webpage. More details about this may be found under the "Invitation Letters" section. The symposium webpage is online and will be populated soon with information on accommodation, registration, submission of abstracts, weather, tourism and other information.
