Current Issues in Quarkonium Production
As a stringent test of the nonrelativistic QCD factorization approach for inclusive heavy-quarkonium production in high-energy hadron collision, the polarized heavyquarkonium production at the Tevatron is discussed. The polarization of prompt J/ψ at the Tevatron is predicted within the nonrelativistic QCD factorization framework. The contribution from radiative decays of P-wave charmonium state...
متن کاملCurrent Issues in Heavy Quark Production
Consider the effect of a charm quark (with mass m) being produced in neutral current DIS. For simplicity we concentrate on virtual photon exchange and neglect the bottom quark. Precise data are now available on F2(x,Q ). In pQCD the operator product expansion and asymptotic freedom allow one to calculate the scaling violations. This is incorporated in the factorization theorem where short dista...
متن کاملTop quark threshold production in γγ collisions : current theoretical issues ⋆
The top quark-antiquark pair threshold production at future High Energy Photon Colliders is considered in view of the recent advances in the theoretical description of the nonrelativistic heavy quark dynamics.
متن کاملClopidogrel Resistance: Current Issues
Antiplatelet agents are mainly used in the prevention and management of atherothrombotic complications. Dual antiplatelet therapy, combining aspirin and clopidogrel, is the standard care for patients having acute coronary syndromes or undergoing percutaneous coronary intervention according to the current ACC/AHA and ESC guidelines. But in spite of administration of dual antiplatelet therapy, so...
متن کاملCurrent Issues in Cancer
In the narrowest sense radiotherapy is a treatment almost exclusively used in managing cancer and based on the use of ionising radiation. In practice, however, the scope of the subject is broad (box 1) as management decisions relating to cancer must be made in the context of a thorough appraisal of the tumour and patient. Tumours are characterised by histogenesis and morphology, and, increasing...
