Lifting Effective-Field-Theory Degeneracies in Semileptonic Heavy-Baryon Decays
Hindi Zouhair
Semileptonic heavy-baryon decays provide a sensitive probe of the helicity structure underlying possible lepton-flavor universality violation in transitions. We…
Null Tests and Lepton Universality in Baryon Decays
Hindi Zouhair
We develop a precision framework for doubly charmed baryon decays based on symmetry-protected observables and effective-field-theory diagnostics. In nonleptonic decays, we…
Global Electroweak Fit Constraints on the Two-Higgs-Doublet Model in Light of the CDF W -Boson Mass
Hindi Zouhair
The recent measurement of the boson mass by the CDF II collaboration exhibits a significant tension with the Standard Model (SM) prediction and other experimental determination…
Dark matter relic abundance from a critical-density instability
Hindi Zouhair
We study a nonstandard dark-matter thermal history in which strong self-interactions give rise to collective many-body effects at high number density, as in strongly interacting qu…
