To whomever changed the title to eliminate the phrase "new physics": that wasn't in any way sensational or editorial. This is a common phrase within the physics community. From the conclusions part of the paper:
>The results presented here disagree with the SM at the 3.4σ level. Together with the measurements by the Belle Collaboration, and the sizable difference between the measured and predicted branching fraction of B− → τ−ντ [35–39], this could be an indication of new physics processes affecting decays with a τ lepton in the final state.
