Since the discovery of the Higgs boson in 2012, detailed studies of its properties have been ongoing. Besides its mass, its width - related to its lifetime - is an important parameter. One way to determine this quantity is by measuring its off-shell production, where the Higgs boson mass is far away from its nominal value, and relating it to its on-shell production, where the mass is close to the nominal value. Here, we report evidence for such off-shell contributions to the production cross section of two Z bosons with data from the CMS experiment at the CERN Large Hadron Collider. We constrain the total rate of the off-shell Higgs boson contribution beyond the Z boson pair production threshold, relative to its standard model expectation, to the interval [0.0061, 2.0] at 95% confidence level. The scenario with no off-shell contribution is excluded at a p-value of 0.0003 (3.6 standard deviations). We measure the width of the Higgs boson as Th = 3.2 (+2.4 / -1.7) MeV, in agreement with the standard model expectation of 4.1 MeV. In addition, we set constraints on anomalous Higgs boson couplings to W and Z boson pairs., Peer reviewed

FIG. 1. Nuclear modification factor of the B+c meson compared to that of light charged hadrons, and B+, Bs and D0mesons, as a function of the measured transverse momentum. The total uncertainty is shown for the B+c meson, whereasthe statistical (bars) and systematic (filled rectangles) uncertainties are shown for the other hadrons., FIG. 2. Nuclear modification factor of the B+c meson compared to that of the ground and first excited states of charmonia and bottomonia, as a function of the measured transverse momentum. The total uncertainty is shown for the B+c meson, whereas the statistical (bars) and systematic (filled rectangles) uncertainties are shown for the other hadrons., Peer reviewed
