Fragmentation in $H \to b \bar{b}$ Processes
I study bottom quark fragmentation in the Standard Model Higgs decay H->b bbar, within the framework of perturbative fragmentation functions. I resum large collinear logarithms ln(m_H^2/m_b^2) in the next-to-leading logarithmic (NLL) approximation, using the DGLAP evolution equations. Soft contri...
