50. An experimentalist's pursuit for the meaning of $m_t$ and $\alpha_s$

The top quark mass $m_t$ and the strong coupling constant $\alpha_s$ are key parameters of the standard model, but they are only known to a precision of 0.3--1%. Together, their values determine the stability of the EW vacuum within the framework of the standard model (i.e. no new particles or fields), but even the meaning of their measured values is under debate: for top quark mass the...

In high energy processes, occur in proton-proton (pp) collisions at the LHC, partons (i.e. quarks and gluons) manifest themselves as hadronic jets. Jets are the perfect experimental tools that can be used to access the underlying partonic processes. The production of jets play a key role to test predictions of perturbative QCD (pQCD) over a wide region in phase space and constrains the parton...
