Hi VubRecoil group,
I am wondering if there might be a mistake in BAD 1383:
(1) In Eq. 8, I think the denominator of the second term should
be raised to the power of n, not 2. Is that correct?
(2) The signal function drawn in Figure 4 LOOKS like it has:
* x_c ~ 5.28 GeV = 5280 MeV
* (alpha*sigma_l) ~ 1 GeV = 1000 MeV
* sigma_l ~ sigma_R1, sigma_R2
However, according to Table 7:
* x_c = 5.2795 GeV = 5279.5 MeV
* (alpha*sigma_l) = 0.000008484 GeV = 0.008484 MeV
* sigma_l << sigma_R1, sigma_R2
I tried to check by plotting the function with the
given fit parameters in ROOT, but it did not work
because ROOT could not handle the exponential
of (x - x_c)/sigma_l, since sigma_l is so tiny.
Am I missing something, or is there a mistake, or what?
Thanks,
sheila
