Vacuum Stability Conditions for Higgs Potentials with Triplets

Gilbert Moultaka, Michel C. Peyranère

Tree-level dynamical stability of scalar field potentials in renormalizable theories can in principle be expressed in terms of positivity conditions on quartic polynomial structure…

Holographic models of composite Higgs in the Veneziano limit. Part I. Bosonic sector

Daniel Elander, Michele Frigerio, Marc Knecht +1

We study strongly-coupled, approximately scale-invariant gauge theories, which develop a mass gap in the infrared. We argue that a large number of fermion flavours is most suitable…

Completeness and Complementarity for , and conversion

Sacha Davidson

Lepton Flavour Violation(LFV) is New Physics that must occur, but is stringently constrained by experiments searching for mu to e flavour change, such as , and…

Probing contact interactions with conversion

Sacha Davidson, Yoshitaka Kuno, Yuichi Uesaka +1

Contact interactions of a muon, an electron and two photons can contribute to the decay , but also to the conversion of a muon into an electron in the electric field of…

Chiral Condensate and Spectral Density at full five-loop and partial six-loop orders of Renormalization Group Optimized Perturbation

Jean-Loic Kneur, André Neveu

We reconsider our former determination of the chiral quark condensate from the related QCD spectral density of the Euclidean Dirac operator, using our Re…
