Highest-mass di-photon event recorded by CMS as of Dec '15 (Run 2, 13 TeV)

This image shows a collision event with the largest-mass photon pair so far observed by the CMS detector in collision data collected in 2015. The mass of the di-photon system is 1.5 TeV. One photon candidate, with a transverse momentum of 530 GeV is reconstructed in the endcap region, while a second...

Sumario:This image shows a collision event with the largest-mass photon pair so far observed by the CMS detector in collision data collected in 2015. The mass of the di-photon system is 1.5 TeV. One photon candidate, with a transverse momentum of 530 GeV is reconstructed in the endcap region, while a second, with a transverse momentum of 400 GeV, is reconstructed in the barrel region. Both photon candidates are consistent with the expectation that they are prompt isolated photons.
