The CMS muon system has played a key role for many physics results obtained from the LHC Run-1 data. During the Long Shutdown (2013-2014) significant upgrades have been carried out on the muon detectors and on the L1 muon trigger. In parallel the algorithms for muon reconstruction and identification have been improved for both the High-Level Trigger and the offline reconstruction. Results of...

The luminosity of the LHC will increase up to 2 and 7x10^34 cm-2s-1 after long shutdowns in 2019 and 2025 (phase-1 and phase-2 upgrades). In order to cope with the increased particle fluxes, upgrades are envisioned for the ATLAS muon spectrometer. At phase-1, the current innermost stations of the ATLAS muon endcap will be upgraded with 2x4-layer modules of Micromega detectors, sandwiched by...
