This is the Proceedings of the Second International Summer School in High Energy Physics, focusing on “Standard Model and Beyond”, we have held in M¯ gla, Turkey, on 25–30 September 2006. The participants were mostly graduate and post-graduate students (about 50) working on the experimental and phenomenological problems. The s- dents were mostly Turkish, and there were some from Azerbaijan. In addition to excellent tutorial lectures on the Standard Model and the GrandUnification,therewereexposuresonthecurrentdevelopmentsonheavy—avor physics, the physics at LHC, recent experimental data coming from BABAR and BELLE, as well as neutrino oscillations data, which were p- sented by the senior spoke-persons of TEXONO Collaboration. Encouraged by the success of this year’s event, as well as the preceding one, we are planning to make this school an annual event, with substantial - ternational student participation, and with special focus to those from central Asian countries. Wethinkweowealottothevenuewheretheeventhasbeenheld. Thes- cial location of the convention center where the event has been held, G¨ okova, within half an hour driving distance from Ephesus and Milethos, has been superbly praised by the international participants. These great heritages from antique Ionia are the home of some of our founding fathers of western ci- lization and science, from Thales to Heraklitos. There is another event which already gained the status of a world event, namely the G¨ okova School on Geometry and Topology which uses the same venue. This success story plays a weighted role in our encouragement.
