Cubic color charge correlator in a proton made of three quarks and a gluon

2022

The three point correlation function of color charge densities is evaluated explicitly in light cone gauge for a proton on the light cone. This includes both $C$-conjugation even and odd contributions. We account for perturbative corrections to the three-quark light cone wave function due to the emission of an internal gluon which is not required to be soft. We verify the Ward identity as well as the cancellation of UV divergences in the sum of all diagrams so that the correlator is independent of the renormalization scale. It does, however, exhibit the well known soft and collinear singularities. The expressions derived here provide the $C$-odd contribution to the initial conditions for hi…

Stronger C -odd color charge correlations in the proton at higher energy

2023

The non-forward eikonal scattering matrix for dipole-proton scattering at high energy obtains an imaginary part due to a $C$-odd three gluon exchange. We present numerical estimates for the perturbative Odderon amplitude as a function of dipole size, impact parameter, their relative azimuthal angle, and light-cone momentum cutoff $x$. The proton is approximated as $\psi_\mathrm{qqq}|qqq\rangle + \psi_\mathrm{qqqg}|qqqg\rangle$, where $\psi_\mathrm{qqq}$ is a non-perturbative three quark model wave function while the gluon emission is computed in light-cone perturbation theory. We find that the Odderon amplitude increases as $x$ decreases from 0.1 to 0.01. At yet lower $x$, the reversal of t…

Charged-particle multiplicities in proton–proton collisions at √s = 0.9 to 8 TeV

2017

A detailed study of pseudorapidity densities and multiplicity distributions of primary charged particles produced in proton–proton collisions, at √s = 0.9, 2.36, 2.76, 7 and 8 TeV, in the pseudorapidity range |η| < 2, was carried out using the ALICE detector. Measurements were obtained for three event classes: inelastic, non-single diffractive and events with at least one charged particle in the pseudorapidity interval |η| < 1. The use of an improved track-counting algorithm combined with ALICE’s measurements of diffractive processes allows a higher precision compared to our previous publications. A KNO scaling study was performed in the pseudorapidity intervals |η| < 0.5, 1.0 and 1.5. The …

Manufacturing export performance and public capital: an analysis by country technology position

2021

The objective of this paper is to examine the relationship between public capital and manufacturing export performance. It also aims at investigating whether this relationship depends on the proximity of a country's technology frontier. To achieve this, we adopted a methodology that estimates the elasticities of public capital as a non-rival factor in a model that considers factor intensity as a mechanism of industrial development. We use an interaction model with panel data from 1999 to 2014 across 35 advanced and less advanced countries. Our results show that in countries far from the technology frontier, public capital accumulation is an element of industrial development as opposed to co…

I comportamenti devianti nel contesto di lavoro

2019

The main purpose of this chapter is exploring a review on the concept of organizational deviance, a series of behaviors promoted by individuals in contradiction with their own moral standards and in contrast to organizational rules.

Reliability of adapted version of Italian Label tobacco Impact Index for the adolescent: ALII

2017

OBJECTIVE: The aim of this study is to assess the reliability of the Adolescent Label Impact Index (ALII) , it is an adolescent adapted version of Italian LII of the tobacco products warnings. MATERIAL AND METHODS: A sample including students aged 13-15 years was considered. The ALII is constructed by 4 items: salience, harm, quitting and forgo. The questionnaire was self-administered to study participants twice with 3 days between each administration (T1 and T2) to measure reliability. The internal consistency using Cronbach's alpha and Corrected Item-Total Correlations (CITC) and the test-retest reliability applying Pearson's correlation were computed. RESULTS: Cronbach's alpha ranges fro…
