[BDXlist] [EXTERNAL] BDX: PAC51 jeopardy presentation

[Andrea Celentano]

Dear Marco,
the slides are to me very clear. Here are my comments.

Slide n. 6, in top-left figure the words are mirrored?
Slide n. 8, we only considered positrons resonant annihilation.
Slide n. 11, the sentence “World exclusion limits are mainly the same as 5y ago” is to me not appropriate. The NA64 experiment just completed a run with ~ 1E12 EOT, and the new limits are definitively stronger than those reported in the slide (https://urldefense.proofpoint.com/v2/url?u=https-3A__arxiv.org_abs_2307.02404&d=DwIFaQ&c=CJqEzB1piLOyyvZjb8YUQw&r=Ru7nA6zPBSFajtw1o6aZjchIV9Cs2SBk2RiVldzQhDc&m=iUGl7h3vyanOGh3BiR_HoD9T0eUl2w6Nls4zpv-vc4f2DlK5MeSlrkkUs6n4Kj0n&s=rabeMbyGCtI2LlU9W1Lq71kYwllIPJFA5v7lptNUzy8&e= ).
These results for the moment are only on arXiv (PRL paper was submitted one week ago), so we can probably not mention them. However, I would remove this sentence (note that the latest published NA64 results are from 2021 PRD letter: https://urldefense.proofpoint.com/v2/url?u=https-3A__arxiv.org_abs_2108.04195&d=DwIFaQ&c=CJqEzB1piLOyyvZjb8YUQw&r=Ru7nA6zPBSFajtw1o6aZjchIV9Cs2SBk2RiVldzQhDc&m=iUGl7h3vyanOGh3BiR_HoD9T0eUl2w6Nls4zpv-vc4f2DlK5MeSlrkkUs6n4Kj0n&s=b6KsW7NUJkWOwJbY1NPDTcY0KmvYrLi8c-h78r8vvwE&e= , 2 years ago)


Bests,
Andrea
