AB The Standard Model (SM) of particle physics is the currently established theoreticalframework which describes, at a fundamental level, interactions among elementary particles.The construction of high-energy colliders such as the Large Hadron Collider(LHC) at CERN, the largest particle accelerator ever built, allowed scientists to testtheir models at increasingly high energy scales. In recent years, the LHC has increasinglyfocused its attention on the precise measurements of SM processes, as they playa crucial role in the exploration of new physics. The emphasis on precision physicshas also motivated the development of the high luminosity (HL) LHC upgrade, andthe proposal of new high precision machines such as the FCC-ee. In this context, thetheoretical effort has to match the experimental work, because precise measurementsrequire an equal precision of the SM predictions. This argument applies also to theoriesBeyond the Standard Model (BSM), and it becomes particularly relevant in the case ofEffective Field Theories (EFTs), where higher-order corrections can significantly impactthe bounds on new physics. The main focus of this thesis is the precision calculationof processes in the SM and Standard Model Effective Field Theory (SMEFT) framework,including gg → HH, Drell Yan production qq → ll, and electroweak observables.Finally, the ultimate goal is to make accurate predictions that can be tested on futurecolliders, such as HL LHC and Fcc-ee. The study of this area is very important, and itgives crucial information on the structure of new physics beyond the SM.
