Cabibbo angle anomalies and a global fit to vector-like quarks
Matthew Kirk
The most recent determinations of from superallowed beta decays lead to a discrepancy when compared to the value implied by mesonic CKM measurements combined with CKM unit…
A window onto leptoquarks?
Matthew Kirk, Shohei Okawa, Keyun Wu
Upcoming neutrino telescopes promise a new window onto the interactions of neutrinos with matter at ultrahigh energies (- GeV), and the possibility to detect de…
Minimal model for the -boson mass, , and quark-mixing-matrix unitarity
Andreas Crivellin, Matthew Kirk, Anil Thapa
The triplet scalar with hypercharge predicts a positive definite shift in the mass, w.r.t.~the Standard Model prediction, if it acquires a vacuum expectation va…
Global Fit of Modified Quark Couplings to EW Gauge Bosons and Vector-Like Quarks in Light of the Cabibbo Angle Anomaly
Andreas Crivellin, Matthew Kirk, Teppei Kitahara +1
There are two tensions related to the Cabibbo angle of the CKM matrix. First, the determinations of from , , and decays disagree at the level.…
Unveiling Hidden Physics at the LHC
Oliver Fischer, Bruce Mellado, Stefan Antusch +30
The field of particle physics is at the crossroads. The discovery of a Higgs-like boson completed the Standard Model (SM), but the lacking observation of convincing resonances Beyo…
First-Generation New Physics in Simplified Models: From Low-Energy Parity Violation to the LHC
Andreas Crivellin, Martin Hoferichter, Matthew Kirk +2
New-physics (NP) constraints on first-generation quark-lepton interactions are particularly interesting given the large number of complementary processes and observables that have…
