I am currently working on Higgs physics analysis at the ILC, especially the channel of Higgs boson decaying into muon pairs.

Some Notes

Of course, "something_EN.pdf" is a note written in English, and "something_JP.pdf" is written in Japanese (for my convenience :) ).

Note of error propagation

In this note, we will discuss how to calculate the error of reconstructed muon pair mass. In section 1, we will consider the case of two muons only. In section 2, the case of two muons plus correction of FSR photon is considered. The calculation itself is not so difficult, but contains too many terms. Now, you don't need to drink 10 cups of coffee or beer for the calculation. {OK} :-?

Series of analysis note

This note summarizes the first analysis log of h-->mumu channel at 500 GeV ILC, using SGV samples and fully-simulated samples for signal in both cases. To summarize in one sentence, I obtained the precision of 54%(34%) with the case of full(SGV) samples.

This is a second log of h-->mumu analysis at 500 GeV. I obtained similar precision compare to note 01 even I increased the statistics of MC samples.

Changing order of words/numbers

Consider you have a following data format in file1. (format: from left, "process", "beam polarization", "process ID", and "cross section")

2f eL.pR 250001 14.68
X750 eL.pR 134567 0.88

If you want change the order like;

250001 2f eL.pR 14.68
134567 X750 eL.pR 0.88

(new format: from left, "process ID", "process", "beam polarization", and "cross section")

In this case, awk command will help you. Just type;

awk '{ print $3" "$1" "$2" "$4 }' file1 > file2
less file2

Now you got it. You need " ", otherwise all characters/numbers are combined, not separated with space.
