Crawling technicolor
O. Catà, R. J. Crewther, Lewis C. Tunstall
We analyze the Callan-Symanzik equations when scale invariance at a nontrivial infrared (IR) fixed point is realized in the Nambu-Goldstone (NG) mode. As a res…
Probing lepton flavour (universality) violation at NA62 and future kaon experiments
Lewis C. Tunstall, Andreas Crivellin, Giancarlo D'Ambrosio +1
Recent results from the LHC's first run have revealed intriguing departures from lepton flavour universality in the semi-leptonic decays of -mesons. We discuss the complementary…
Dispersive treatment of and
Gilberto Colangelo, Ramon Stucki, Lewis C. Tunstall
We analyse the rare kaon decays and $(\ell = e \mbox{ or } μ)$ in a dispersive framework in which the weak Hamiltonian carries momentum. Our an…
Stop searches in flavourful supersymmetry
Andreas Crivellin, Ulrich Haisch, Lewis C. Tunstall
Natural realisations of supersymmetry require light stops , making them a prime target of LHC searches for physics beyond the Standard Model. Depending on the kinemat…
Lepton flavor (universality) violation in rare kaon decays
Andreas Crivellin, Giancarlo D'Ambrosio, Martin Hoferichter +1
Recent anomalies in the decays of mesons and the Higgs boson provide hints towards lepton flavor (universality) violating physics beyond the Standard Model. We observe that fou…
Status of Chiral-Scale Perturbation Theory
R. J. Crewther, Lewis C. Tunstall
Chiral-scale perturbation theory PT has been proposed as an alternative to chiral perturbation theory which explains the rule for kaon dec…
