We construct the Lagrangian for an effective theory of highly energetic quarks with energy Q, interacting with collinear and soft gluons. This theory has two low energy scales, the transverse momentum of the collinear particles, p⊥, and the scale p 2 ⊥/Q. The heavy to light currents are matched onto operators in the effective theory at one-loop and the(More)
We construct an effective field theory valid for processes in which highly energetic light-like particles interact with collinear and soft degrees of freedom, using the decay B → Xsγ near the endpoint of the photon spectrum, x = 2Eγ/mb → 1, as an example. Below the scale μ = mb both soft and collinear degrees of freedom are included in the effective theory,(More)
Recent data from the CDF collaboration on the production of spin-triplet bottomonium states at the Tevatron pp̄ collider are analyzed within the NRQCD factorization formalism. The color-singlet matrix elements are determined from electromagnetic decays and from potential models. The color-octet matrix elements are determined by fitting the CDF data on the(More)

Autologous platelet-gel (APG) is the process of harvesting ones own cells (platelets), concentrating them most often through centrifugation, exposing them to an agonist which induces activation which releases intrinsic substances, and applying them to a target area to accelerate wound healing. APG is attractive because it concentrates a large number of(More)

The main aim of this study was to obtain a profile of the dietary behaviours of workers and to explore possible barriers to change. A self-administered, questionnaire was completed by 2528 people employed in seven worksites in the industrial, educational and health sectors. The results of the food frequency section are reported here related to sex, social(More)
In this paper we discuss the systematics of quarkonium production at the LHC. In particular, we focus on the necessity to sum logs of the form log(Q/p⊥) and log(p⊥/mQ). We show that the former contributions are power suppressed, while the latter, whose contribution in fragmentation is well known, also arise in the short distance (i.e., non-fragmentation)(More)
