There were some events at 750 GeV, resembling a second Higgs boson. As we all know, the first Higgs boson, with a mass of 125 GeV, saturates a theoretical bound (vacuum stability), and so it is encouraging to read
here of a scenario in which 750 GeV is the theoretical upper bound on the mass of a second Higgs. However, within that scenario, the upper limit is correlated with another parameter in a way that is ruled out empirically. Therefore, by numero-logic, this was a false alarm and we can all go back to sleep.
