Hello Tim and Andrea,
<div class=""><br class="">
</div>
<div class="">The link was the correct one, yes I referred to NA64 results, and yes I know it is invisible decay search. Still thought to send as the region is close to our visible search.</div>

am one of the authors of this paper: as Tim says, this is related to the Dark Sector scenario in which the A’ decays invisibly to LDM; this model is different from the one searched for by HPS, and thus the results from NA64 do not introduce any new constraint
on HPS parameters space.</span><br style="caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;" class="">

Hi Stepan,<br class="">
<br class="">
Perhaps the wrong link was sent? This paper is a missing energy search for dark matter (a la LDMX), not visibly decaying dark photons - it cannot exclude anything in the visible search parameter space. (Any visible decay will be vetoed in this search.)<br class="">

The new results from NA64 cuts very close to our overtaxing region!<br class="">

here is the new paper (still in the Arxiv) that reports a huge new exclusion limit<br class="">
