Graduate Highest loop order of experimental relevance?

[Vanadium 50]

Could you point me to a good reference for this?

The original NLO paper was (Paulo) Nason, (Sally) Dawson, and (R. Keith) Ellis, around 1989. It builds on a paper a few years earlier by (John) Collins, (Dave) Soper and (Jack) Smith where they derive the relevant factorization theorems. Matteo Cacciari was giving talks about LO, NLO and the state of the art about ten years ago; if you find a conference proceedings by him that references one or both of the above papers, that's probably as good as you are going to get in one place.

Thanks. Maybe slide 12 in

• Matteo Cacciari: "(Theoretical) review of heavy quark production" BNL 14/12/2005 (pdf)

has the kind of statement that you are referring to.

I think the slides as a whole give a reasonable view of the heavy flavour state of the art. Slide 5 is a motivation for NNLO (and why N3LO may play only a minor role).

Right, sorry, I meant slide 12 (I was pointing somebody else to slide 5 for another reason, and mixed up the numbers when writing here).

I am trying to pinpoint the statement which you were referring to above when you wrote:

...heavy flavor production. The NLO contributions are about the same size as the LO contributions, and the scale dependence is actually worse at NLO than LO.

I'm sorry, but that's a little unfair. "Here's an article I found - why can't I find a statement you made in it?"

I think I did a pretty good job of pointing you in the right direction, but it may well be that a single document that has everything you want doesn't exist. But if a literature search needs to be done, I don't think I am the one who needs to do it.

that's a little unfair.

There is some misunderstanding here. But never mind.
