Dihadron interference fragmentation functions in proton-proton collisions
We study the production of hadron pairs in proton-proton collisions, selecting pairs with large total transverse momentum with respect to the beam, and small relative transverse momentum, i.e., belonging to a single jet with large transverse momentum. We describe the process in terms of dihadron fragmentation functions. We consider the production of one pair in polarized collisions (with one tr...
متن کاملSoft - Collinear - Effective - Theory
We analyze the charmless two-body B → V P decays in the soft-collinear-effective-theory (SCET), where V (P ) denotes a light vector (pseudoscalar) meson. Using the current experimental data, we find two solutions in χ fit for the 16 non-perturbative inputs responsible for the 87 B → PP and B → V P decay channels in SU(3) symmetry. Chirally enhanced penguins can only change several charming peng...
متن کاملSoft Collinear Effective Theory
In this talk I review soft collinear effective theory. After a discussion of the formalism and properties of the effective field theory, I turn to phenomenology. I present results on colorsuppressed B → D decays, and on the Υ radiative decay spectrum.
متن کاملAspects of four-jet production in polarized proton-proton collisions.
We examine the intrinsic spin-dependence of the dominant gg → gggg subprocess contribution to four-jet production in polarized proton-proton collisions using helicity amplitude techniques. We find that the partonic level, longitudinal spin-spin asymmetry, âLL, is intrinsically large in the kinematic regions probed in experiments detecting four isolated jets. Such events may provide another qual...
