@johncarlosbaez Doesn’t it limit the cross-section more so than the mass?

@AstroMikeHudson - I don't know why their press release phrases it in terms of the mass: there must be extra assumptions put in, to get that conclusion. Maybe it's simply because no journalist could understand "cross section". Here's a graph they released which more accurately conveys what they actually found. The horizontal axis is mass in GeV/𝑐², and the proton mass is about 1 GeV/𝑐².

@johncarlosbaez @AstroMikeHudson What I would like is a graph of uncertainity in the cross-section as a function of the number of days the experiment has run. That would be fun.

@abdullahkhalids - yes. They are driving the cross-section down to zero. The experiment has run for 220 days, and they plan to go on for 1000 days.

(I said 280 days in my post, but that includes 60 days of an earlier run.)
