Run 1 and Run 2 (Large Hadron Collider)

Run 1 and Run 2 refer to two major periods of operation at the Large Hadron Collider (LHC), the world's largest particle accelerator. Run 1 (2010-2013) focused on discovering fundamental particles, notably the Higgs boson, by colliding protons at energies up to 8 TeV. Run 2 (2015-2018) increased collision energies to 13 TeV, enabling more detailed studies of particle physics, searching for new phenomena beyond the Standard Model, and exploring the universe's fundamental forces. Each run involved extensive data collection and analysis to deepen our understanding of the universe's basic constituents.
