Particle Cake Although it is just a hint, LHCb physicists are baffled as to why the production of electrons, muons and taus should be defying Standard Model predictions. According to decay measurements, electrons were produced 25 percent more often than muons. If the Standard Model were a cake recipe, it would be like throwing all the ingredients for a chocolate cake into a bowl, baking it and then getting a vanilla cake out of the oven. Obviously there's something not quite right with the cake recipe.

In 2013, Discovery News reported on a related LHCb finding that there is a discrepancy in the decays of B-mesons. B-mesons, which are hadrons composed of a quark and anti-quark, decay in a very specific way and physicists noticed a non-random pattern in the angular distribution of decay products that was not predicted by the Standard Model. Once again, the recipe appears to be slightly askew.
Could there be some commonality between these two findings? Last year, LHCb physicists suggested that supersymmetry may have a part to play in the B-meson results and the same could be said for the lepton decay products in this latest work.
