“…Topics dealt with are: new thresholds beyond the mass of the Higgs boson, and associated violation of lepton and baryon number; chirality and anomaly constraints; a prediction for the top quark mass and the value of the light quark mass scale; heavy fermions and cosmological baryon production at temperatures near 1 TeV. (13 refs).…”

“…The following subjects were illustrated: flavour chiral symmetry for quarks and leptons; extending a global into a local symmetry: the basic structure of a Yang-Mills theory; the search for the weak interaction group from earlier data: SU(2)(X)U(1); spontaneous symmetry breaking and the masses of W, Z, and the fermions; grand unification: the case of SU(5); and proton instability, neutrino and neutron oscillations. (7 refs).…”

“…The $H \to \tau \tau$ decay is an important decay mode of the Higgs boson as it allows to measure directly the Higgs coupling to fermions. This paper presents the measurement of the $H \to \tau \tau$ cross-section and a test of $CP$ invariance in the Higgs boson production performed in the same channel. …”

“…The analysis of the free energy, using the set of gap equations which determines the width of the Gaussian terms, is sufficient to show that this symmetry breaking happens only when the fermionic terms are included and is absent in the bosonic case.…”

Superspace gives a geometric picture of supersymmetry and provides a technique for finding representations of the supersymmetry algebra by fields. …”

“…This is the first ever NNLO calculation of an observable with more than two colored partons, and/or massive fermions, at hadron colliders. Augmenting our fixed order calculation with soft-gluon resummation through Next-to-Next-to-Leading Logarithmic (NNLL) accuracy, we observe that the predicted total inclusive cross-section exhibits a very small perturbative uncertainty, estimated at +-2.7%. …”

“…To illustrate the impact on QCD-scale ALP phenomenology, we consider the scenario where the ALP-gluon coupling is dominant over the ALP coupling to photons, electroweak bosons, and all fermions for mπ≲ma≲3  GeV. We emphasize, however, that our method can easily be generalized to any set of ALP couplings to standard model particles. …”
