Contribution
It proposes a new flux tube-based model for string breaking in QCD, including predictions for potential, string length, and temperature effects.
Findings
Predicted the form of the long-range potential.
Estimated the string breaking length.
Forecasted the temperature dependence of string breaking near deconfinement.
Abstract
We present a model for string breaking based on the existence of chromoelectric flux tubes. We predict the form of the long-range potential, and obtain an estimate of the string breaking length. A prediction is also obtained for the behaviour with temperature of the string breaking length near the deconfinement phase transition. We plan to use this model as a guide for a program of study of string breaking on the lattice.
