02:30:17	Gilberto Colangelo:	I guess it was not my question, but it's a good one!
02:30:45	Martin Hoferichter:	The PDG numbers are not pole parameters.
02:31:09	Martin Hoferichter:	The pole parameters are known as given in https://arxiv.org/abs/1107.1635
02:31:27	Martin Hoferichter:	I.e., 0.2% in the mass, 1.5% in the width.
02:32:49	Martin Hoferichter:	The PDG parameters are reaction dependent and thus not very meaningful.

2nd Break

03:57:04	Bogdan MALAESCU:	Just to follow-up on Martin’s remark: I emphasised the 2pi channel in my statement just because of the tensions between the experimental measurements, making the exercise non-trivial. Otherwise, other contributors are of course relevant too.
04:06:00	Steven Gottlieb:	Why not just compare C(t) at specific values of t, say 0.4, 0.7, 1.0. 1.75, 2.5 fm?
04:07:02	Zoltan Fodor:	Statistically less strong
04:09:22	Ruth Van de Water:	@Steve, because I also am not sure how to compare correlator results  — which are necessarily at fixed lattice spacing — from different discretizations.
04:10:33	kmiura:	@ Steven: Do you mean a "fixed" t or very narrow window of t? For that, taking continuum limit is not easy.
04:10:35	Steven Gottlieb:	@Ruth, we would still have to look at continuum limit.
04:11:15	Martin Hoferichter:	I'm not sure it's possible to define a Euclidean time window that focuses on 2pi alone. At least for the current window the tails are pretty large. 
04:12:06	Peter Boyle:	Can’t you fit the correlation function and interpolate?
04:12:13	Peter Boyle:	Prior to continuum limit
04:12:58	Ruth Van de Water:	@Martin, the Mainz group has shown that a 4-state reconstruction from pipi states reproduces the correlator above t~2.3 fm.  To me, that indicates that this region is dominated by 2pi states.  But maybe I’m missing something?
04:13:22	Hartmut Wittig:	But this is a volume-dependent statement
04:14:40	Ruth Van de Water:	@hartmut, agreed.  I just mean that the fact that the pipi tail is long doesn’t mean that we can’t come up with a reasonable choice for a window that is mostly from pipi states?
04:16:52	Zoltan Fodor:	We have used 0.4-1.0; 1.0-1.6; 1.6-2.5; 2.5 - inf for the windows; they give good statistical significance
04:17:55	Ruth Van de Water:	@zoltan, those sound very reasonable to me — I was thinking about even simplifying to 1.0-2.5 and2.5-inf
04:18:52	Zoltan Fodor:	@Ruth, Once we have 1.0-1.6 and 1.6-2.5 we also have 1.0-2.5, so everything is OK
04:20:35	Ruth Van de Water:	@zoltan, indeed.  :)
04:27:05	Christoph Lehner:	Sounds good Laurent
04:38:22	Ruth Van de Water:	When are we doing the group photo?
04:38:28	Christoph Lehner:	tomorrow
04:38:42	Ruth Van de Water:	Okay — phew!  :)
04:41:48	kmiura:	Aubin et al 19 is too large?
