I discuss the implications of the long-standing anomaly in semitauonic B meson decays for new physics (NP) searches at high-pT with ATLAS and CMS detectors. Effective field theory is used to identify potential signatures at high energies correlated with the anomaly. Several representative models put forward to explain the anomaly are examined in details: color-neutral vector triplet, 2HDM, scalar and vector leptoquark model. We find that in general τ +τ − searches impose serious challenge to NP explanations of the anomaly. After recasting present 8 and 13 TeV analyses stringent limits are set on all the models.
