MEASUREMENT OF THE ZZ PRODUCTION CROSS SECTION IN pp COLLISIONS AT

The ZZ production cross section in proton–proton collisions at 13 TeV center-of-mass energy is measured using 3.2 fb−1 of data recorded with the ATLAS detector at the Large Hadron Collider. The considered Z boson candidates decay to an electron or muon pair of mass 66–116 GeV. The cross section is measured to be 29.7 −3.6(stat.) +1.0 −0.8(syst.) +1.7 −1.3(lumi.) fb in a fiducial phase space ref...

A Measurement of the Cross Section for Four Pion Production in Yy Collisions at Spear*

We present a measurement of the cross section for the reaction e+e-f e+e-?r'rr-7;frat SPEAR. This channel is found to be large and dominated by the process yy + pop0 + -+-t-frTrTTr. The cross section, which is small just above the four pion threshold, exhibits a large enhancement near the p ' ' p threshold. * Work supported in part by Department of Energy, contracts DE-AC03-76SF00515 and W-7405...
