A Note on the $k_T$-Factorization for Exclusive Processes
F. Feng, J.P. Ma, Q. Wang
TL;DR
This paper critically examines the $k_T$-factorization approach for exclusive processes, demonstrating that it suffers from gauge dependence and inconsistency, thus questioning its validity in theoretical predictions.
Contribution
The paper provides a detailed analysis revealing the gauge dependence and inconsistency of the $k_T$-factorization method for exclusive processes.
Findings
$k_T$-factorization is gauge-dependent.
The approach is inconsistent for exclusive processes.
Questions the reliability of $k_T$-factorization in this context.
Abstract
We show in detail that the -factorization for exclusive processes is gauge-dependent and inconsistent.
