DESCRIPTION:Prof. Arttu Rajantie (Imperial College)\nMagnetic monopoles ar
 e among the theoretically most interesting hypothetical particles that are
  being searched for. However\, this is hampered by their strong magnetic c
 harge\, because of which their production cross section in proton-proton c
 ollisions cannot be computed using perturbation theory. In this talk\, I w
 ill discuss a different production mechanism: Schwinger pair production. J
 ust like electron-position pairs would be produced in a strong electric\, 
 a sufficiently strong magnetic field would produce monopole-antimonopole p
 airs\, if they exist. The rate of this process can be computed even at str
 ong coupling and is largely independent of their microscopic details. Ther
 efore it can give reliable\, universal mass bounds that apply to all types
  of monopoles. The strongest magnetic fields in the Universe are in magnet
 ars and in heavy ion collision experiments\, and I will discuss the bounds
  arising from them as well as the theoretical challenges in obtaining reli
 able and accurate results from heavy ion collisions carried out in Novembe
 r 2018 at the LHC.
