Missing-mass search in forward-proton-tagged dilepton events with the ATLAS detector
Georges Aad, Erlend Aakvaag, B M. Acharya, Mariano Apicella et autres
A search is conducted in proton-proton collisions at the Large Hadron Collider for photon-induced production $pp\rightarrow pp+ γγ, (γγ\rightarrow VX)$ of a visible particle $V$ decaying into a pair of same-flavour charged leptons ($e^+e^-$ or $μ^+μ^-$) and an undetected invisible component $X$. …
