Is The Standard Model Failing Us In The Bs Sector? Not Really, Say New Tevatron Results

It feels good, for a die-hard sceptic like I am, to live and let unexplained phenomena die. The phenomena in question are measured deviations from the predictions of the Standard Model (SM), our wonderful theory of subnuclear interactions, which has been c ...

Who Underestimates Their Systematic Uncertainties?

It is a well-known fact that it is much easier to measure a physical quantity than to correctly assess the magnitude of the uncertainty on the measurement: the uncertainty is everything! A trivial demonstration of the above fact is the following. Consider ...
