Studying the Sivers function by model calculations
A. Courtoy, S. Scopetta, V. Vento
A formalism is presented to evaluate the Sivers function in constituent quark models. A non-relativistic reduction of the scheme is performed and applied to the Isgur-Karl model. T…
Skyrmions at finite density and temperature: the chiral phase transition
Byung-Yoon Park, Hee-Jung Lee, Vicente Vento
The Skyrme model, an effective low energy theory rooted in large QCD, has been applied to the study of dense matter. Matter is described by various crystal structures of skyr…
Model calculations of the Sivers function satisfying the Burkardt Sum Rule
A. Courtoy, S. Scopetta, V. Vento
It is shown that, at variance with previous analyses, the MIT bag model can explain the available data of the Sivers function and satisfies the Burkardt Sum Rule to a few percent a…
The Physics of Glueballs
Vincent Mathieu, Nikolai Kochelev, Vicente Vento
Glueballs are particles whose valence degrees of freedom are gluons and therefore in their description the gauge field plays a dominant role. We review recent results in the physic…
Monopolium production from photon fusion at the Large Hadron Collider
Luis N. Epele, Huner Fanchiotti, Carlos A. Garcia Canal +1
Magnetic monopoles have attracted the attention of physicists since the founding of the electromagnetic theory. Their search has been a constant endeavor which was intensified when…
Sivers function in constituent quark models
S. Scopetta, A. Courtoy, F. Fratini +1
A formalism to evaluate the Sivers function, developed for calculations in constituent quark models, is applied to the Isgur-Karl model. A non-vanishing Sivers asymmetry, with oppo…
Sivers Asymmetry for the proton and the neutron
S. Scopetta, A. Courtoy, F. Fratini +1
A formalism is presented to evaluate the Sivers function in constituent quark models. A non-relativistic reduction of the scheme is performed and applied to the Isgur-Karl model. T…
The Role of the Dilaton in Dense Skyrmion Matter
Byung-Yoon Park, Mannque Rho, Vicente Vento
In this note, we report on a remarkable and surprising interplay between the omega meson and the dilaton chi in the structure of a single skyrmion as well as in the phase structure…
A quark model analysis of the Sivers function
A. Courtoy, F. Fratini, S. Scopetta +1
We develop a formalism to evaluate the Sivers function. The approach is well suited for calculations which use constituent quark models to describe the structure of the nucleon. A…
