Bounds on Transverse Spin Asymmetries for Lambda Baryon Production in pp Collisions at BNL RHIC
D. de Florian, J. Soffer, M. Stratmann +1
We study inclusive Lambda hyperon production in pp collisions at BNL RHIC, with just one transversely polarized proton. We show that the measurement of the spin transfer between th…
The light-cone gauge and the calculation of the two-loop splitting functions
A. Bassetto, G. Heinrich, Z. Kunszt +1
We present calculations of next-to-leading order QCD splitting functions, employing the light-cone gauge method of Curci, Furmanski, and Petronzio (CFP). In contrast to the `princi…
Next-to-leading Order Evolution of Transversity Distributions and Soffer's Inequality
W. Vogelsang
We present a calculation of the two-loop splitting functions for the evolution of the twist-2 `transversity' parton densities of transversely polarized nucleons. We study the impli…
Next-to-Leading Order Evolution of Polarized and Unpolarized Fragmentation Functions
M. Stratmann, W. Vogelsang
We determine the two-loop 'time-like' Altarelli-Parisi splitting functions, appearing in the next-to-leading order Q^2-evolution equations for fragmentation functions, via analytic…
A Rederivation of the Spin-dependent Next-to-leading Order Splitting Functions
W. Vogelsang
We perform a new calculation of the polarized next-to-leading order splitting functions, using the method developed by Curci, Furmanski and Petronzio. We confirm the results of the…
Spin-dependent non-singlet structure functions in next-to-leading order
M. Stratmann, A. Weber, W. Vogelsang
We study in detail the flavor-non-singlet component of polarized structure functions in the framework of a consistent and complete next-to-leading order ( analysis.…
