Detailed Description

The mean Energy loss per unit length of a particle is calculated as

\( (dE/dx) = (dE/dX)_{io} + (dE/dX)_{rad} \)

Formulas used:

\( (dE/dX)_{io,mip} = K \cdot \frac{Z}{A} \frac{1/\beta^2} \cdot [\frac{1}{2}] \cdot \ln \frac{2 m_e c^2 \beta^2 \gamma^2 T_max}{I^2} - \beta^2] \), (1)

respectively

@f$ (dE/dX)_{io,e}  = \frac{1/2} \cdot K \cdot \frac{Z}{A}
[2\ln\frac{2m_e c^2}{I} + 3 \ln{\gamma} - 1.95] @f$ (2)

Alternatively, the most probable value instead of the mean value can be

taken (steared by boolean in the method signature), taken from (4)

 @f$ \_{L}\Delta_p = \xi \left[ln\frac{2mc^2\beta^2\gamma^2}{I} +

ln\frac{\xi}{I} - 0.8 + 4.447 \right] \( with \) \xi = Z N_a \frac{k}{\beta^2}\codt t \( The with of both distributions is given as the (crude) approximation, that the full width at half maximum of the landau distribution is : \) 4 \xi \( For the transformation into a parameterized sigma the factor \) 2\cdot\sqrt{2.\cdot ln(2.) } \( can be used Sigma can be multiplied by a form factor (given through job options) - <b>For radiation corrections: </b> The Bethe-Heitler parameterisation is in terms of \) Z = \frac{E_f}{E_i} \( (2) With this parameterisation the expected energy loss \) \langle Z \rangle = e^{-t} \( (2) where \) t = \frac{x}{X_0} \( or the fraction of a radiation length of material traversed by the particle. This formula can be transposed in terms of \) \Delta (E) \(. The transposition however depends on the direction of propagation. For forwards propagation we get: \) \langle \Delta (E) \rangle = E_i ( 1 - \langle Z \rangle ) \( (2) For the propagation against momentum we get: \) \langle \Delta (E) \rangle = E_i ( \frac{1}{\langle Z \rangle} - 1 ) \( (2) The variance of Z is also defined (2): \) Var(Z) = e^{-t ln(3) / ln(2)} - e^{-2t} \( Transposing this one dervies the following relations for 1. Forwards propagation \) Var ( \Delta \frac{q}{p} ) = \frac{Var(Z)}{\langle Z \rangle ^2 p^2} \( 2. Backwards propagation \) Var ( \Delta \frac{q}{p} ) = \frac{Var(Z)}{p^2} \( Where p is the global momentum. Bethe-Heitler formula \) (dE/dX)_{rad} = \frac{E_{initial}}{X_o}\cdot (\frac{m}{m_e})^2
