QCD measurements in pp collisions / Meena, Meena (Strasbourg, IPHC) /ALICE,ATLAS,CMS and LHCB Collaborations
Quantum Chromodynamics (QCD) plays a fundamental role in describing the dynamics of high energy proton-proton collisions at the Large Hadron Collider. As the dominant interaction in these collisions, QCD governs both signal processes and complex backgrounds that must be understood and controlled. [...]
