DOI: 10.1007/jhep05(2021)179
Abstract: Abstract CP violation in charm decay was observed in the decays D0→ P±P∓ of a D0 meson to two pseudoscalars. When interpreted within the SM, the results imply that the ratio of the relevant rescattering… read more here.

DOI: 10.1103/physrevd.100.054001
Abstract: We discuss production of cc¯-pairs within kT-factorization approach (off-shell initial partons) with unintegrated parton distribution functions (uPDFs). We present a consistent prescription which merges the standard leading-order (LO) kT-factorization calculations for this process with tree-level… read more here.
