A bstract A search for exclusive or quasi-exclusive W+ W− production by photon-photon
interactions, pp→ p (*) W+ W− p (*), at\(\sqrt {s}= 7\) TeV is reported using data collected by …

A bstract The existence of an axion-like particle (ALP) would induce anomalous scattering of
light by light. This process can be probed at the Large Hadron Collider in central exclusive …

Searches for exclusively produced W boson pairs in the process pp (γ γ)→ p W+ Wp and an
exclusively produced Higgs boson in the process pp (gg)→ p H p have been performed …

The goal of this whitepaper is to give a comprehensive overview of the rich field of forward
physics. We discuss the occurrences of BFKL resummation effects in special final states …

The anomalous magnetic moment of the tau lepton a τ=(g τ-2)/2 strikingly evades
measurement but is highly sensitive to new physics such as compositeness or …

A bstract Axion-like particles (ALPs) interacting with the Standard Model can be abundantly
produced in proton beam fixed-target experiments. Looking for their displaced decays is …
