A bstractHeavy quark parton distribution functions (PDFs) play an important role in several Standard Model and New Physics processes. Most analyses rely on the assumption that the charm and bottom PDFs are generated perturbatively by gluon splitting and do not involve any non-perturbative degrees of freedom. It is clearly necessary to test this hypothesis with suitable QCD processes. Conversely, a non-perturbative, intrinsic heavy quark parton distribution has been predicted in the literature… 

Non-perturbative bottom PDF and its possible impact on new physics searches

Heavy quark parton distribution functions (PDFs) play an important role in several Standard Model and New Physics processes. Most PDF analyses rely on the assumption that the charm and bottom PDFs

On the intrinsic heavy quark content of the nucleon

We demonstrate that to a very good approximation the scale-evolution of the intrinsic heavy quark content of the nucleon is governed by non-singlet evolution equations. This allows us to analyze the

Role of the intrinsic charm content of the nucleon from various light-cone models on γ+c-jet production

Having a precise knowledge of the charm quark component can lead to a better understanding of the fundamental structure of the nucleon. Furthermore, the charm quark distribution function plays an

The latest CTEQ6.6 parton distributions, obtained by global analysis of hard-scattering data in the framework of general-mass perturbative QCD, are employed to study theoretical predictions and their

Comment on "New Limits on Intrinsic Charm in the Nucleon from Global Analysis of Parton Distributions".

Intrinsic heavy quarks in hadrons emerge from the non-perturbative structure of a hadron bound state and are a rigorous prediction of QCD, indicating significant intrinsic charm and strangeness probabilities.

Leptoproduction of Heavy Quarks

There are presently two approaches to calculating heavy quark production for the deeply inelastic scattering process in current literature. The conventional fixed-flavor scheme focuses on the flavor

We investigate the charm sector of the nucleon structure phenomenologically, using the most up-to-date global QCD analysis. Going beyond the common assumption of purely radiatively generated charm,
