Comments on the physics working group
Dear Ryan and Joe -
thanks for getting things going yesterday with the meeting.
I wanted to add a few additional comments. First, with regard
to high-impact channels, my feeling has always been that
in addition to the pi1, some of the spin-2 states are also high
on my list:
For the pi1:
[1] gamma p -> p pi_1[0]
[2] gamma p -> n pi_1[+]
decays: 3pions: [1] pi+ pi- pi0 ; [2] pi+ pi+ pi- and pi+ pi0 pi0
b1 pi: [1] b1+ pi- + cc ; [2] b10 pi+
f1 pi: [1] f1 pi0; [2] f1 pi+
for the h2:
[1] gamma p -> p h2
decays: [1] b1+pi- +cc, b10,pi0, rho+pi- + cc, rho0 pi0
for the b2:
[1] gamma p -> p b2[0]
[2] gamma p -> n b2[+]
decays [1] b2 -> a2+ pi - + cc ; [2] b2[+] -> a2[+]pi0 + a2[0]pi+
This tends to indicate that the 3pi and the b1pi final states are probably
our highest impact channels. Thus:
p pi+ pi- pi 0
n pi+ pi+ pi-
n pi+ pi0 pi0
p b1[+] pi- -> p omega pi+ pi-
p b1[0] pi0 -> p omega pi0 pi0
n b1[0] pi+ -> n omega pi0 pi+
I also have a number of articles that people might find useful linked to my web site
