(I conclude from the lack of mention in my current and previous universities' news -- wot, no Tara Shears? -- that at least their LHCb groups weren't significantly involved!)
Officially, all qualified members sign all papers. The names of the people who worked on an analysis are not publicised. There is already a preference to only work on analysis, because it's cheap and easy (no need to send people to CERN or kit-out expensive labs), but that doesn't help much in the way of actually collecting data, so "service work" shouldn't be discouraged by attributing extra credit to people doing analysis.
Institutes sometimes write press releases such as this where they exaggerate their involvement. In this instance, only 2 out of 10 people in the analysis group are affiliated to Oxford. It's very disingenuous not to acknowledge that they're part of a larger collaboration.
