A Python package for flavour physics phenomenology in the Standard model and beyond
As part of the study of LFV quarkonium decays in [2207.10913](https://arxiv.org/abs/2207.10913) we calculated and implemented quarkonium decays in flavio. We would like to make it publicly available and am thus...
This PR fixes issue #185 by using the prefactor VtdVts* instead of VtsVtd*.
This is the (second) pull request aiming to fix the problems in calculations od LFV kaon decays to leptons, based on discussion in #138. (I'm aborting my original PR #140...
Hi, Flavio basis convention (https://wcxf.github.io/assets/pdf/WET-3.flavio.pdf) for s -> d nunu transition has CKM factor (Vts* Vtd) in operators' definition. But in flavio implementation, amplitude for K -> pi nu nu...
Starting the implementation of Lb->L(1520)ll. Up to now, it is not ready!
As discussed with @MJKirk in https://github.com/flav-io/flavio/issues/172 it would be nice to change the implementation of epsilon_K to the more recent and more precise results from https://arxiv.org/abs/1911.06822.
For a long time we have been using version 1.5.0, which produces a SM uncertainty for the observables Rtaul(B->Dlnu) and Rtaul(B->D*lnu) of 0.006 and 0.003 respectively, which are similar to...
Hi, I think I've found two problems in the implementation of K0->ll' in flavio/physics/kdecays/kll.py. ### Lepton flavour violating K-short decay results in errors `K=KS` together with `l1 != l2` not...
Hi all, we are using flavio to generate and fit heavily. Since we perform many toys, speed becomes a critical issue for us and we started looking into possible ways...
This is mostly a record of theory citations I know/ believe to be missing from flavio right now (as taken from my comment in the middle of the pull request:...
