A Kinematic Condition on Intrinsic Charm

Abstract

We derive a kinematic condition on the resolution of intrinsic charm and discuss phenomenological consequences.

Figures (2)

• Figure 1: Left panel: Normalized intrinsic charm distribution with finite $m_p$; Right panel: ratio of the probability distribution for intrinsic charm including the effect of the proton mass to the case $m_p/M_Q \rightarrow 0$. The parameter $c$ is given by $c \simeq 0.348$ and $M_Q = 1.59~\rm GeV$ in the pole mass scheme Alekhin:2012vu.
• Figure 2: Full line: lower boundary in $Q^2/\rm GeV^2$ for which $\rho(x) \geq 5$ as a function of $x$. Long dashed line: lower boundary for extrinsic charm production resulting from Eq. (\ref{['eq:TLIVex']}) also for $\rho(x) \geq 5$; Short dashed line: highest $Q^2$-bin of the EMC experiment Aubert:1985fx.
