The discovery of the Higgs boson in 2012 has crowned decades of research to complete the Standard Model and to explain how the mass of elementary particles is generated. This discovery set the stage for LHC Run 2 in 2015-2018. The increased energy (13 TeV p-p collisions) and the collected data statistics (~10 times that of Run1) opened new territories: heavier particles, rarer processes become accessible. LHC Run 3 with 13.6 TeV p-p collisions started in 2022, further increasing the physics reach. Leading the MTA-ELTE Lendület CMS Particle and Nuclear Physics Group, I contribute to the test of the Standard Model via electroweak precision measurements and to the direct search for new physics suggested by theoretical arguments and observational hints, such as the lack of a consistent theory of quantum gravity, the naturalness problem and the existence of dark matter and dark energy. The coming years hold the promise of furthering our knowledge of the secrets of elementary particles and could bring new discoveries!
