Effect of dipole size fluctuations on diffractive photo-production of vector mesons
Jean-Paul Blaizot, Marco Claudio Traini
We consider the diffractive photo-production of vector mesons on a proton, in the dipole model. We take into account the effect of the fluctuations of the the dipole size, whose ma…
Signatures of excited monopolium
Huner Fanchiotti, Carlos A. Garcia-Canal, Marco Traini +1
We study electromagnetic properties of particles with magnetic moment and no charge using their behavior when traversing coils and solenoids. These particles via the Faraday-Lenz l…

Huner Fanchiotti}, C. A. ~García Canal, Marco Traini +1
We study the detection of particles with magnetic moment and no charge by using coils and solenoids. The detector uses the Faraday-Lenz law to create a current whose energy is meas…
Scattering of charged particles off monopole-antimonopole pairs
Vicente Vento, Marco Traini
The Large Hadron Collider is reaching energies never achieved before allowing the search for exotic particles in the TeV mass range. In a continuing effort to find monopoles we dis…
