Glimpses of Collider Experiments (Past, present and future)

The early collider experiments took place during early 70's both in electron-positron and proton-proton collisions. From mid 70's they become the centre stage for new discoveries, starting from charm, gluon, top and finally Higgs boson. I shall present a few examples of such experimental setups - both historical and modern. There is a tendency to make general purpose detectors with large solid angle coverage and to optimize as a search machine for new physics. One of the later ones in the scenario is the Compact Muon Solenoid detector (CMS) which was desgned as a general purpose detector at the Large Hadron Collider (LHC). One of the primary tasks of the LHC experiments was to find the Higgs boson, the last missing element of the Standard model. This task has been fulfilled during 2012 with the announcement of discovery Higgs boson like object by CMS and ATLAS.
