I am experimenting and playing around with some data, and I'm having trouble seeing how to generate invariant mass plots.
The data I have has a bunch of events, and variables such as
etc.. but no energy. There is a histogram which generates the
invariant mass, but no macro provided for this. For example, I know
there are tracks for electrons and protons (TPC), and I want to see
if there are any pairs as a result of
. Conceptually I need to loop over all positive negative pairs,
and plot the histogram. I should get a peak around zero for ? pair
production. The invariant mass formula is
But there is no data for the energy, how do the high energy physicists do it? Do they guess some value for the energy and make plots with that guess?
Without knowing more about your data set I can only offer a few random suggestions:
If you have some kind of PID reason to believe that the tracks
might be electron you just assume that they are and compute the
energy from the momentum and .
In you have a calorimeter in the detector stack you measure the
energy, and project the maximum likelihood energy loss back to the
vertex. Note, however that the measured signal may have error much
larger than , so it may be better
to use the device for PID and fall back on the previous

I have to make an Inventory excel sheet and I'm having some trouble trying to figure out how to calculate the "Balance on Hand." Here are the instructions: The Inventory scenario is based on a fictitious custom bike builder. Of course, the data given for the scenario is a small sampling of what a shop’s inventory would be. The data represents an end of month quantity and is being used to determine, the balance on hand and which items need...
I'm having trouble getting my balance to equal for the unadjusted balance. Also how do I create the adjusted trial balance?
