[G12] p K+ K- exclusive events

[Saini, Mukesh]

Hi Lei,

The Dalitz Plot is labelled incorrectly. It IS Mass of (proton K-) and not Mass of (proton K+).

I am running simulations for phi cross-sections right now but I have the K+K- setup and will run them as soon as the phi gets done. So I won't be able to show the comparison tomorrow though, but next Tuesday.

Mukesh.

Hi, Mukesh,

Your moments stuff are very very  interesting. Have you looked at moments for simulation, assuming you have simulated events with M(K+K-) between 1 and 2 GeV?

On you dalitz plots, the y axis is M(pK-), not M(pK+), right?

Hi All,

As per Tuesdays discussion -

1. Comparison of a Gaussian Fit, Breit-Wigner Fit and a Voigtian Fit and counting the phi mesons in the peak with the background fit extended over a larger mass range.

With the Old MM:

The Difference between the MM Cuts for Selected Phi events (Invariant Mass of K+K- between 1.010,1.030 GeV):

2. Plots of Masses, t, t-prime, Moments for K+K- with Various sets of Cuts like:
    a. Beam Energy 3.6 GeV and 4.4 GeV
    b. Without Lambda_1
    c. Without Lambda_2
    d. Without phi meson
    e. t-prime cuts

3. Dalitz Plot for K+ K- vs proton K- with the same cuts listed above:
http://hadron.physics.fsu.edu/~mukesh/files/pKKExc/Dalitz_4.4GeV.pdf<http://hadron.physics.fsu.edu/%7Emukesh/files/pKKExc/Dalitz_3.6GeV.pdf>

We will discuss these Tuesday but since I am always short those 2 important plots, Please let me know what they are.

Mukesh.
