Observation of B0 Meson decays to a1(1260) pi
B. Aubert, BaBar Collaboration
We present a preliminary measurement of the branching fraction of the B meson decay B0--> a1(1260)+ pi- with a1(1260)+ --> pi+ pi+ pi- . The data were recorded with the BaBar detec…
Asymmetric Statistical Errors
Roger Barlow
Asymmetric statistical errors arise for experimental results obtained by Maximum Likelihood estimation, in cases where the number of results is finite and the log likelihood functi…
A note on Delta ln L = -1/2 Errors
Roger Barlow
The points at which the log likelihood falls by 1/2 from its maximum value are often used to give the `errors' on a result, i.e. the 68% central confidence interval. The validity o…
Asymmetric Systematic Errors
Roger Barlow
Asymmetric systematic errors arise when there is a non-linear dependence of a result on a nuisance parameter. Their combination is traditionally done by adding positive and negativ…
Systematic Errors: facts and fictions
Roger Barlow
The treatment of systematic errors is often mishandled. This is due to lack of understanding and education, based on a fundamental ambiguity as to what is meant by the term. This n…
