Monopole condensation ans superconductivity: the case
L. Del Debbio, A. Di Giacomo, G. Paffuti +1
We study the behaviour of a suitably defined disorder parameter, showing for the first time monopole condenssation in the ground state of QCD.
Monopole condensation in the ground state of gauge theories: a disorder parameter
L. Del Debbio, A. Di Giacomo, G. Paffuti
We construct a disorder parameter for dual superconductivity of the ground state of gauge theory.
Field-strength correlators in gauge theory
L. Del Debbio, A. Di Giacomo, Yu. Simonov
We measure field-strength and their correlators in presence of a static pair by numerical simulations. We give an interpretation of these data in terms of quadratic and…
Detecting Dual Superconductivity in the Ground State of Gauge Theory
L. Del Debbio A. Di Giacomo, G. Paffuti
We explicitly construct a monopole creation operator: its vacuum expectation value is an order parameter for dual superconductivity, in that, if different from zero, it signals a s…
The spin content of the proton in quenched QCD
B. Alles, M. Campostrini, L. Del Debbio +3
We present preliminary results on the proton spin structure function at zero momentum, in the quenched approximation. Our calculation makes use of a nonperturbative means of determ…
