Detailed Description

This task is designed to read in MC truth information about the energy loss in each strip, and then fit the distributions from secondaries and primaries separately.

Then (this is not implemented yet) it tries to deconvolve the contributions from secondaries and primaries separately from the total sum energy loss distribution, and in that way estimate the secondary to primary charge particle ratios per \(\eta\) bin. If the same procedure is applied to real data, then we can have an estimate - from data - of the ratio of secondaries to primaries and thus perhaps get a clearer picture of the secondary particle contamination.

The the function fitted to the (scaled) energy loss ( \(\Delta/\Delta_{mip}\) distributions is

\[ F(\Delta;\Delta_p,\xi,\sigma,\mathbf{a}) = \sum_{i=1}^{N}a_i f(\Delta;\Delta_i,\xi_i,\sigma_i) \]

where \( a\) is of length \( N\) and

\[ f(\Delta;\Delta,\xi,\sigma) = \int_{-\infty}^{+\infty}d\Delta' L(\Delta,\Delta',\xi) \frac{1}{\sqrt{2\pi\sigma^2}} e^{-\frac{(\Delta'-\Delta_mp^2}{2\sigma^2}} \]

and

\[ \Delta_i = i(\Delta_1+\xi\log(i))\\ \xi_i = i\xi_1\\ \sigma_i = \sqrt{i}\sigma_1\\ a_1 = 1\\ \Delta_p = \Delta_1\\ \xi = \xi_1\\ \sigma = \sigma_1 \]
