I agree, it should be complementary.</div>

In their search they assumed the invisible decay: A'-><span style="font-family: sans-serif; font-size: 12.32px; text-align: left; display: inline !important; color: rgb(32, 33, 34); background-color: rgb(248, 249, 250);" class="ContentPasted0">χ</span>χ decay,
so this exclusion, doesn't exclude existence of an A' with an epsilon within our range that decays visibly.</div>

<div dir="ltr">Hi Rafo,
<div><br>
</div>
<div>Thanks for sending this around. It looks like their exclusion limit fully contains our experiment. Our experiment should still be considered complementary though given that we are not using a missing mass method. It may be useful for us to consider putting
more emphasis on our sensitivity to neutrals though, given this.</div>
