  402. Making a cross check I found out that our geometry is surprisingly higher than last year:
  403. \begin{enumerate}
  404. \item MC11: $17.28\%$
  405. \item Sim08a: $19.14\%$
  406. \end{enumerate}
  407. Didn't believe that $2\%$ is due to the higher CM energy.

  411. I run Generator Level MC to studied what has changed. Turns out this is pythia fault:
  412. \begin{enumerate}
  413. \item MC11, pythia6: $17.28\%$
  414. \item Sim08a, pythia6: $17.96\%$
  415. \item Sim08a, pythia6: $19.14\%$
  416. \end{enumerate}
  417. To make story more funny this is true for all MC samples. With Jon Harrison we checked yesterday: $B_s\to \mu \mu$, $D_s \to \eta \mu \nu $ etc.
  418. We will let Gloria know about this. Does this change something in $B_s\to \mu \mu$?
