Hadron Physics: a World of Colour

Structure

Innovating in the Supercomputing Era to obtain new pictures of the interior of hadrons

There is a large variey of data on spectral and structural modifications of hadrons, induced by high energy collisions, produced in experiments as ALICE, CMS, ATLAS, COMPASS, HADES/GSI. More data will emerge from GLUEX at JLab, and PANDA at GSI. 

It is critical to transform these data into knowledge and images of possible mechanisms and structures.

Our group has developed an innovative method which provides a tomographic analysis of mass and spin distribution inside the hadrons, that does not need to be formulated in the infinite momentum frame, enabling us to have density pictures with evolving energy.

A proof of principle that our toolset is calculable and has predictive power was our recent calculation of the pion form factor.

Our relativistic approach in Minkowski enables us to perform direct calculations of the transition form factor for baryons and mesons in the timelike region, and no further work is needed to extend results obtained with Euclidean metric.

Two main features of our approach are:

  1. it considers dynamical quarks, that is to say that it makes a consistent treatment  the quark mass function and the quark-antiquark interactions.
  2. it uses LQCD data to constrain the quark-antiquark interaction, mass functions and mass distributions. These features will enable us to extract from LQCD data information on mechanisms and quark-quark dynamics.
