Thermal and hard scales in transverse momentum distributions, fluctuations, and entanglement

Fluctuations and Transverse Momentum Distributions in the Color Clustering Approach

We present our results on transverse momentum fluctuations, multiplicity fluctuations and transverse momentum distributions for baryons and mesons in the framework of the clustering of color sources. We determine under what conditions the initial state configurations can lead to color connection, and more specifically, if variations of the initial state can lead to a transition from disconnecte...

Transverse momentum fluctuations and percolation of strings

The peculiar behaviour of the transverse momentum fluctuations with the centrality of the collision shown by the Relativistic Heavy Ion Collider data is naturally explained by the percolation of strings. In this framework, the pT fluctuations are nothing but fluctuations on the number of overlapping strings that form clusters in a heavy ion collision. According to this idea, the fluctuations sh...

Top Quark Transverse Momentum and Rapidity Distributions

Intrinsic transverse momentum in hard processes

In this contribution I discuss transverse momentum dependent quark distributions and their operator structure. Some of the experimental signatures in particular in Drell-Yan scattering are given.

Entanglement properties and momentum distributions of hard-core anyons on a ring

We study the one-particle von Neumann entropy of a system of N hard-core anyons on a ring. The entropy is found to have a clear dependence on the anyonic parameter which characterizes the generalized fractional statistics described by the anyons. This confirms that the entanglement is a valuable quantity for investigating topological properties of quantum states. We derive the generalization to...
