[G12] new secondary beam observation

[Amaryan, Moskov]

Hi John,

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

Best regards,
Moskov.

Hi Moskov:

This plot (the one I sent out just now) has completely revamped my
research program here.  I'm now interested in looking into basically
anything I can do with a beam *other* than a photon or an electron.

So, yeah.  It's on the list.  A K_s will travel something like 2-3 cm
before decaying (c-tau=2.7cm), which is comparable to the mean path it
will have through the target before leaving out of the cylindrical wall.
This gives us a reasonable chance of seeing it do something interesting
other than decay.

Now I just need to find 6-7 more students...  :)

Hi John,


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


Best regards,
Moskov.

Hi all:

It occurs to me that, if we can observe Lambda-proton elastic
scattering
in g12, we should also be able to see something easier like
proton-proton scattering.  I looked over the data again, requiring
only
two protons in the final state, and plotted the missing mass in "X p
-->
p p".  The attached resulting plot has approximately 1.2 million
events
in the peak above background.

We don't have a g12 meeting this week, but I thought y'all might
like to
see this.  My life is getting interesting...

John
