OPE for B-meson distribution amplitude and dimension-5 HQET operators
Hiroyuki Kawamura, Kazuhiro Tanaka
The -meson light-cone distribution amplitude (LCDA) is defined as the matrix element of a quark-antiquark bilocal light-cone operator in the heavy-quark effective theory (HQET)…

Double Transverse-Spin Asymmetries for Small-Q_T Drell-Yan Pair Production in p\bar{p} Collisions
Hiroyuki Kawamura, Kazuhiro Tanaka
We discuss the double-spin asymmetries in transversely polarized Drell-Yan process, calculating all-order gluon resummation corrections up to the next-to-leading logarithmic accura…

Double Transverse-Spin Asymmetries for Drell-Yan Process in pp and p\bar{p} Collisions: Role of Nonleading QCD Corrections at Small Transverse Momentum
Hiroyuki Kawamura, Kazuhiro Tanaka
We discuss the double-spin asymmetries in transversely polarized Drell-Yan process, calculating all-order gluon resummation corrections up to the next-to-leading logarithmic accura…
