flav-io/flavio: v1.5.1

Published July 19, 2019 | Version v1.5.1

Software Open

This minor release fixes a few issues and updates parameters, but also brings two minor new features.

New features

All classes wiith named instances, i.e. Measurement, Parameter, Observable, Implementation, AuxiliaryQuantity and a few others have a new find method which takes a regular expression as input and returns all matching instance names. This has powerful applications, e.g. finding all observables in tau decays:
```
flavio.Observable.find('tau->')
```
or all observables that are total branching ratios in decays with a tau in the final state:
```
flavio.Observable.find('^BR.*->.*tau')
```
Combining this with get_measurements introduced in 1.5.0, this allows finding observables and their measurements without browsing the source files.
The Parameter class now pretty prints in a Jupyter notebook. Try flavio.Parameter['m_b'].

Bugs fixed

The shift due to dimension-6 contributions to the Fermi constant in electroweak precision observables contained ann erroneous factor of 2 for one Wilson coefficient (68ec2c41e7898c8732a044ebbe5283198221e09e)
The NP contributions to the W mass were off by a factor of 2

Measurements
