Bayesian uncertainty quantification of perturbative QCD input to the neutron-star equation of state [PDF]
Journal of High Energy Physics, 2023 The equation of state of neutron-star cores can be constrained by requiring a consistent connection to the perturbative Quantum Chromodynamics (QCD) calculations at high densities.

Extraction of the x-dependence of the non-perturbative QCD b-quark fragmentation distribution component [PDF]
Phys.Lett. B580 (2004) 108-118, 2003 Using recent measurements of the b-quark fragmentation distribution obtained in $e^+e^- \to b \bar{b}$ events registered at the Z pole, the non-perturbative QCD component of the distribution has been extracted independently of any hadronic physics modelling. This distribution depends only on the way the perturbative QCD component has been defined. When

, 2001 A review on how the Odderon idea does appear in QCD is given. In the last years it has been developed a non-perturbative QCD approach based on the stochastic vacuum model and a perturbative one based on resummation techniques in the small x QCD region.

Mirror QCD and Cosmological Constant
Universe, 2017 An analog of Quantum Chromo Dynamics (QCD) sector known as mirror QCD (mQCD) can affect the cosmological evolution due to a non-trivial contribution to the Cosmological Constant analogous to that induced by the ground state in non-perturbative QCD.

Tests of hard and soft QCD with e+e- Annihilation Data [PDF]
Nucl.Phys.Proc.Suppl. 109B (2002) 87-92, 2001 Experimental tests of QCD predictions for event shape distributions combining contributions from hard and soft processes are discussed. The hard processes are predicted by perturbative QCD calculations. The soft processes cannot be calculated directly using perturbative QCD, they are treated by a power correction model based on the analysis of infrared

Thoughts about the utility of perturbative QCD in the cores of neutron stars – contribution to a roundtable discussion on neutron stars and QCD [PDF]
EPJ Web of Conferences, 2022 In this contribution, I discuss the utility that perturbative QCD offers in studying the matter in the cores of neutron stars. I discuss the reasons why perturbative QCD can constrain the equation of state at densities far below the densities where we ...
