The discovery of the Higgs boson at the Large Hadron Collider (LHC) at the CERN laboratory in Geneva, Switzerland, has confirmed the mechanism for the origin of masses in the Standard Model, but at the same time poses several newer questions. Despite direct searches, no evidence for new physics signals at the LHC has yet been observed. The probing of new physics will become more stringent through the High Luminosity upgrade of the LHC (HL-LHC) planned to begin in 2026.\u00a0 Several sub-systems of the ATLAS detector at the LHC will be upgraded, most notably the charged particle tracker will be replaced by a new system of about 200 m^2 of silicon sensors that can cope with the harsh HL-LHC conditions. In addition, the ATLAS Collaboration is developing novel radiation-hard technologies based on monolithic silicon detectors (HV\/HR-CMOS) for possible use in the tracker.\u00a0 Furthermore, state-of-the art technologies capable of precision tracking and timing (Low Gain Avalanche Diodes – LGAD) are being investigated to help identify primary collisions from background events. The research and development of these new detectors could have profound consequences for future tracking and timing detectors in particle physics experiments as well as for future instrumentation in high radiation environments. These novel silicon-based technologies will be presented together with the expected physics reach of the HL-LHC.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
