Heavy Quarkonium Inclusive Decays : Theoretical Status and Perspectives / Vairo, Antonio (CERN)
I review some recent progress and open problems in the calculation of heavy-quarkonium inclusive decay widths into light particles in the framework of QCD non-relativistic effective field theories..

Quarkonium Photoproduction at Next-to-leading Order / Maltoni, Fabio (CERN) ; Mangano, Michelangelo L. (CERN) ; Petrelli, Andrea (INFN, Pisa)
We present the calculation of O(as^2 aem) corrections to heavy-quarkonium total photoproduction cross-sections. Results are given for the colour-octet component of S and P waves. [...]

Production of heavy quarks and heavy quarkonia / Schuler, Gerhard A. (CERN)
Uncertainties in the next-to-leading-order calculations of heavy-quark ($Q$) production are investigated. Predictions for total cross sections, single-inclusive distributions of heavy quarks and heavy flavoured hadrons, as well as for $Q\bar{Q}$ correlations, are compared with charm and bottom data. [...]

New predictions for inclusive heavy-quarkonium P-wave decays / Brambilla, Nora (INFN, Milan ; Milan U.) ; Eiras, Dolors (Barcelona U., ECM ; Barcelona, IFAE) ; Pineda, Antonio (Karlsruhe U., TTP) ; Soto, Joan (Barcelona U., ECM ; Barcelona, IFAE) ; Vairo, Antonio (CERN)
We show that some NRQCD colour-octet matrix elements can be written in terms of (derivatives of) wave functions at the origin and non-perturbative universal constants once the factorization between the soft and ultrasoft scale is achieved by using an effective field theory where only ultrasoft degrees of freedom are kept as dynamical entities. This allows us to derive a new set of relations between inclusive heavy-quarkonium P-wave decays into light hadrons with different principal quantum number and with different heavy flavour. [...]

Perspectives of heavy-quarkonium production at FCC-ee / He, Zhi-Guo (Hamburg U., Inst. Theor. Phys. II) ; Kniehl, Bernd A (Hamburg U., Inst. Theor. Phys. II)
Due to its non-relativistic nature, heavy quarkonium constituted by heavy quark-anti-quark pairs (Q ¯ Q = b ¯ b or c¯ c) is an ideal object to investigate bothperturbative and non-pertative aspects of QCD. The non-relativistic QCDfactorization formalism [1] built on the rigorous effective field theory [2]provides a powerful tool to systematically calculate heavy-quarkonium productionand decay. [...]
