High Luminosity Large Hadron Collider

 * Nominator(s): Betelgeuse496 (talk) 05:20, 13 August 2021 (UTC)

This article is about an upgrade to the Large Hadron Collider. It covers all aspect related to the motivation of the project, its physics goals, timeline, and discusses all facts related to the upgrade technology to the machine itself and of the experiments involved Betelgeuse496 (talk) 05:20, 13 August 2021 (UTC)
 * Oppose out of process nom. The instruction at the top of the page state An editor is allowed to be the sole nominator of only one article at a time, but two nominations may be allowed if the editor is a co-nominator on at least one of them., but this is the nominator's second solo nomination in less than 24 hours.  The article also contains uncited text such as "The upgrades to the heavy-ion injectors are also in progress and would bring up even more opportunities to observe very rare phenomena and to search for BSM physics.", "The motivation for the construction of large underground infrastructure at HL-LHC therefore, is to have a high efficiency and highly reliable machine which can deliver the required integrated luminosity.", and several other spots.  Doesn't meet WP:FACR #1c due to lack of inline citations in places.  I'm also concerned about #1c's " it is a thorough and representative survey of the relevant literature", as the majority of the sources are from the group running the project (CERN), and ideally FAs should have less reliance on non-independent sources.

 * Coord note -- Since I've archived the earlier nom HF refers to, the out-of-process issue is dealt with but the concerns re. sourcing remain; for now I'll leave this open for further comments or responses. Cheers, Ian Rose (talk) 08:12, 13 August 2021 (UTC)


 * Suggest withdrawal. In addition to the sourcing issues noted by HF, the article's overall organization needs improvement and there are significant prose issues (eg "The HL-LHC upgrade being applicable to almost all major LHC experiments has a wide of physics goals").

 * Not at the moment. The overall structure needs more work and detector upgrades need more detail. The integrated luminosity doesn't need to be in the lead, instantaneous luminosity would fit there (it's a better measure of accelerator performance). The instantaneous luminosity shouldn't be in "introduction" and its description needs to be less confusing. In addition it's currently only discussing ATLAS and CMS values, that needs to be mentioned. Luminosity leveling can be mentioned somewhere (it's hinted at in the beam optics section with a confusing description). The whole article needs proofreading - typos, missing spaces, strange statements like "proton beams with double the original luminosity", ... but that can follow after the larger work is done. --mfb (talk) 16:13, 15 August 2021 (UTC)


 * Closing comment -- Thanks all. Recommend trying Peer Review after addressing reviewers' comments, after which (providing a minimum of two weeks has passed, per FAC instructions) the article could be renominated here. Cheers, Ian Rose (talk) 21:45, 15 August 2021 (UTC)
