Sažetak

Although the Standard Model works extremely/ surprisingly well there  
has been found five barely statistically significant small deviations  
mainly of the type of violations of lepton flavour universality. We  
interpret these anomalies as effects of non-perturbative effects due  
to the top-Yukawa coupling being of order unity in such a way that it  
can cause some sort of severe non-perturbative effect; e.g. there  
could be some bound state of top-quarks and Higgs particles held  
together by the rather strong top-Yukawa coupling. We keep a bit  
abstract w.r.t. what the non-perturbative effect really is due to and  
rather fit by a single parameter K (at least order of magnitude-wise)  
the five anomalies found. Our model predicts too strong effects for  
mixing of mesons like B-mesons even after some reasonable attempt to  
repair this type of predictions.
