A search for exclusive two-photon production via photon exchange in proton-proton collisions, pp → pγγp with intact protons, is presented. The data correspond to an integrated luminosity of 9.4 fb−1 collected in 2016 using the CMS and TOTEM detectors at a center-of-mass energy of 13 TeV at the LHC. Events are selected with a diphoton invariant mass above 350 GeV and with both protons intact in the final state, to reduce backgrounds from strong interactions. The events of interest are those…

Hadron Collider Probes of the Quartic Couplings of Gluons to the Photon and $Z$ Boson
We explore the experimental sensitivities of measuring the gg → Zγ process at the LHC to the dimension-8 quartic couplings of gluon pairs to the Z boson and photon, in addition to comparing them with
Phenomenology of a Born-Infeld extension of the U(1)Y sector at lepton colliders
In this work we perform a non-linear extension of the U(1)Y sector of the Standard Model leading to novel quartic effective interactions between the neutral gauge bosons. We study the induced effects

TLDR
The measurement of the luminosity recorded by the CMS detector installed at LHC interaction point 5, using proton-proton collisions at s = 13 TeV in 2015 and 2016, is reported, and are among the most precise luminosity measurements at bunched-beam hadron colliders.
