<div>Hi John,</div>
<div><br>
</div>
<div>Thanks for your message.</div>
I just wanted to say that although K_s has a c\tau = 2.3 cm and may interact before decaying (your argument),
<div>the K_L will have a chance to interact along the entire target length without a decay.</div>
<div><br>
</div>
<div>In any case I am impressed with your results, good luck.</div>
<div><br>
</div>
<div>Best regards,</div>

The incoming particle could be also K_L, which will survive for much<br>
longer time, as c\tau ~ 15m.<br>

This plot (the one I sent out just now) has completely revamped my<br>
research program here. I'm now interested in looking into basically<br>
anything I can do with a beam *other* than a photon or an electron.<br>
<br>
<br>
So, yeah. It's on the list. A K_s will travel something like 2-3<br>
cm<br>
before decaying (c-tau=2.7cm), which is comparable to the mean path<br>
it<br>
will have through the target before leaving out of the cylindrical<br>
wall.<br>
This gives us a reasonable chance of seeing it do something<br>
interesting<br>
other than decay.<br>
<br>
Now I just need to find 6-7 more students... :)<br>

It is definitely very interesting result. Could you also look at<br>
final<br>
state K_s(\pi^+\pi^-) p and reconstruct the initial K^0?<br>
<br>

It occurs to me that, if we can observe Lambda-proton elastic<br>
scattering<br>
in g12, we should also be able to see something easier like<br>
proton-proton scattering. I looked over the data again,<br>
requiring<br>
only<br>
two protons in the final state, and plotted the missing mass in<br>
"X p<br>
--><br>
p p". The attached resulting plot has approximately 1.2 million<br>
events<br>
in the peak above background.<br>
<br>
We don't have a g12 meeting this week, but I thought y'all might<br>
like to<br>
see this. My life is getting interesting...<br>
