Physics reach of MoEDAL at LHC: magnetic monopoles, supersymmetry and beyond
MoEDAL is a pioneering experiment designed to search for highly ionising
messengers of new physics such as magnetic monopoles or massive (pseudo-)stable
charged particles, that are predicted to exist in a plethora of models beyond
the Standard Model. Its ground-breaking physics program defines a number of
scenarios that yield potentially revolutionary insights into such foundational
questions as, are there extra dimensions or new symmetries, what is the
mechanism for the generation of mass, does magnetic charge exist, what is the
nature of dark matter, and, how did the big-bang develop at the earliest times.
MoEDAL's purpose is to meet such far-reaching challenges at the frontier of the
field. The physics reach of the existing MoEDAL detector is discussed, giving
emphasis on searches for magnetic monopoles, supersymmetric (semi)stable
partners, doubly charged Higgs bosons, and exotic structures such as black-hole
remnants in models with large extra spatial dimensions and D-matter in some
brane theories.Comment: 17 pages, 8 figures; combines two invited talks in 5th International

The effects of rent seeking over tradable pollution permits
The establishment of a tradable permit market requires the regulator to select a level of aggregate emissions and then distribute the associated permits (rent) to specific groups. In most circumstances, these decisions are often politically contentious and frequently influenced by rent seeking behaviour. In this paper, we use a contest model to analyse the effects of rent seeking effort when permits are freely distributed (grandfathered). Rent seeking behaviour can influence both the share of permits which an individual firm receives and also the total supply of permits. This latter impact depends on the responsiveness of the regulator to aggregate rent seeking effort. Using a three-stage game, we show that rent seeking can influence both the distribution of rents and the ex post value of these rents, whilst welfare usually decreases in the responsiveness of the regulator.tradable permit market, rent seeking, initial allocation
