Abstract

We calculate the lowest-order cross-section for Dirac magnetic monopole production from photon fusion ( \( \gamma\) \( \gamma\)in p \( \bar{{p}}\) collisions at \( \sqrt{{s}}\) = 1.96 TeV, pp collisions at \( \sqrt{{s}}\) = 14 TeV, and we compare \( \gamma\) \( \gamma\) with Drell-Yan (DY) production. We find the total \( \gamma\) \( \gamma\) cross-section is comparable with DY at \( \sqrt{{s}}\) = 1.96 TeV and dominates DY by a factor > 50 at \( \sqrt{{s}}\) = 14 TeV. We conclude that both the \( \gamma\) \( \gamma\) and DY processes allow for a monopole mass limit m > 370 GeV based upon the null results of the recent monopole search at the Collider Detector at Fermilab (CDF). We also conclude that \( \gamma\) \( \gamma\) production is the leading mechanism to be considered for direct monopole searches at the Large Hadron Collider (LHC).
