Bottom quarks show odd behavior in LHC data

Science News : The absence of a diphoton signal at 750 GeV dampened the enthusiasm surrounding the release of data analyses from the research teams at the Large Hadron Collider (LHC). But other interesting signals from the particle accelerator are raising eyebrows. The LHCb experiment found that twice as many b hadrons as expected scattered away at an angle from high-energy proton–proton collisions. The unusual behavior is not predicted by the current understanding of quantum chromodynamics (QCD), the theory that explains the interactions of quarks via the strong force. Understanding the behavior may require adjusting certain values in the QCD calculations.
