Important aspects of quantum chromodynamics (QCD) factorization theorems are the properties objects involved that can be identified as universal. One example is definitions parton densities and fragmentation functions for different types hadrons differ only in identity nonperturbative states form matrix elements, but otherwise same. This leads to independence perturbative calculations on details external states. It also lends support interpretations correlation encapsulations intrinsic...

The factorization theorems of quantum chromodynamics (QCD) apply equally well to most simple field theories that require renormalization but where direct calculations are much more straightforward. Working with these simpler is convenient for stress-testing the limits program and examining general properties parton density functions (pdfs) or other correlation might be necessary a factorized description process. With this view in mind, we review steps real scalar Yukawa theory both deep...

Parametrizing TMD parton densities and fragmentation functions in ways that consistently match their large transverse momentum behavior standard collinear factorization has remained notoriously difficult. We show how the problem is solved a recently introduced set of steps for combining perturbative nonperturbative factorization. Called ``bottom-up'' approach previous article, here we call it ``hadron structure oriented'' (HSO) to emphasize its focus on preserving connection model...

We discuss how the quark masses and their mass splitting affect baryons in Skyrme model as well Witten-Sakai-Sugimoto (WSS) model. In both cases, are described by solitonic objects, i.e., Skyrmions instantons, respectively. After quantization of zero modes, nucleons become quantum states a rotor. show affects moment inertia we provide semianalytic approach valid small-mass limit. Additionally, two lightest quarks’ moments Skyrmion induces an isospin breaking effect. This effect turns out not...
