30. Inverse magnetic catalysis from the properties of the QCD coupling in a magnetic field

Prof. Alejandro Ayala

We compute the vacuum one-loop quark-gluon vertex correction at zero
temperature in the presence of a magnetic field. From the vertex function
we extract the effective quark-gluon coupling and show that it grows with
increasing magnetic field strength. The effect is due to a subtle
competition between the color charge associated to gluons and the color
charge associated to quarks, the former...

3. The parton-to-kaon fragmentation functions from global QCD fits at NLO

Roger Hernandez-Pinto (CINVESTAV)

In this talk we revisit the global QCD análisis of the parton-to-kaon fragmentation functions at next-to-leading order accuracy using the latest experimental information on single-inclusive kaon production un electron-positron annihilation, lepton-nucleon deep-inelastic scattering, and proton-proton collisions. An excellent description of all data sets is achieved, and the remaining...
