MoEDAL search in the CMS beam pipe for magnetic monopoles produced via the Schwinger effect / MoEDAL Collaboration
We report on a search for magnetic monopoles (MMs) produced in ultraperipheral Pb--Pb collisions during Run-1 of the LHC. The beam pipe surrounding the interaction region of the CMS experiment was exposed to 184.07 µ b$^{-1}$ of Pb--Pb collisions at 2.76 TeV center-of-mass energy per collision in December 2011, before being removed in 2013.

Search for Highly-Ionizing Particles in pp Collisions During LHC Run-2 Using the Full MoEDAL Detector / MoEDAL Collaboration
This search for Magnetic Monopoles (MMs) and High Electric Charge Objects (HECOs) with spins 0, 1/2 and 1, uses for the first time the full MoEDAL detector, exposed to 6.6 fb^-1 proton-proton collisions at 13 TeV. [...]

MoEDAL-MAPP, an LHC Dedicated Detector Search Facility / MoEDAL-MAPP Collaboration
During LHC's Run-2 the MoEDAL experiment, the LHC's first dedicated search experiment, took over 6 fb^-1 of data at IP8, with p-p and Pb-Pb collisions, operating with 100% efficiency. [...]

Light-by-Light Scattering at Future $e^+e^-$ Colliders / Ellis, John (King's Coll. London ; NICPB, Tallinn ; CERN) ; Mavromatos, Nick E. (King's Coll. London ; Natl. Tech. U., Athens) ; Roloff, Philipp (CERN) ; You, Tevong (CERN ; Cambridge U., DAMTP ; Cambridge U.)
We study the sensitivity of possible CLIC and FCC-ee measurements of light-by-light scattering to old and new physics, including the Heisenberg-Euler Lagrangian in the Standard Model with possible contributions from loops of additional charged particles or magnetic monopoles, the Born-Infeld extension of QED, and effective dimension-8 operators involving four electromagnetic field strengths as could appear in the Standard Model Effective Field Theory. We find that FCC-ee measurements at 365 GeV and CLIC measurements at 350 GeV would be sensitive to new physics scales of half a TeV in the dimension-8 operator coefficients, and that CLIC measurements at 1.4 TeV or 3 TeV would be sensitive to new physics scales {$\sim 2$ TeV or 5 TeV} at 95% CL, corresponding to probing loops of new particles with masses up to $\sim 3.7$ TeV {for large charges and/or multiple species}.

Search for highly-ionizing particles in $pp$ collisions at the LHC’s Run-1 using the prototype MoEDAL detector / MoEDAL Collaboration
A search for highly electrically charged objects (HECOs) and magnetic monopoles is presented using 2.2 fb-1 of p - p collision data taken at a centre of mass energy (ECM) of 8 TeV by the MoEDAL detector during LHC's Run-1. The data were collected using MoEDAL's prototype Nuclear Track Detector array and the Trapping Detector array. [...]

Search for magnetic monopoles produced via the Schwinger mechanism / MoEDAL Collaboration
Schwinger showed that electrically-charged particles can be produced in a strong electric field by quantum tunnelling through the Coulomb barrier. By electromagnetic duality, if magnetic monopoles (MMs) exist, they would be produced by the same mechanism in a sufficiently strong magnetic field. [...]

An Electroweak Monopole, Dirac Quantization and the Weak Mixing Angle / Ellis, John (King's Coll. London ; CERN ; NICPB, Tallinn) ; Hung, P.Q. (Virginia U.) ; Mavromatos, Nick E. (King's Coll. London)
We consider an extension of the Standard Model that was proposed recently by one of the current authors (PQH), which admits magnetic monopoles with a mass of order of a few TeV. We impose, in addition to topological quantization in the SU(2) sector of the model, the Dirac Quantization Condition (DQC) required for consistency of the quantum theory of a charged electron in the presence of the monopole.
