Fit the BES mass of psi(3770) 3.770

Introduction

Compare with the regular fit of 3.774 GeV, we use 3.770 GeV.

Process

We fit the psi(3770) with mass 3.770 GeV¹. Compare with our regular fits which has mass of 3.774 GeV and width 27.5 GeV. The "diff(%)" is calculated by²:

     /   Yields( test  )         \
    |  --------------------  - 1  |  X 100
     \   Yields(regular)         /

; INVALID LISP CODE

Conclusion

The largest difference is 2.40%.
