Abstract:  The pioneering investigation of the fundamental laws of nature at the Large Hadron Collider builds upon the interpretation ofcomplex scattering events. Our ability to identify small signals of elusive new phenomena therefore depends on accurate theoretical simulations which describe …

ABSTRACT: Diverse astrophysical and cosmological observations indicate that most of the matter in the Universe is cold, dark and non-baryonic. Traditionally the most popular dark matter candidates have been new elementary particles, such as WIMPs and axions. However Primordial Black …

Abstract: The explicit breaking of the PQ symmetry by higher dimensional operators can spoil the dynamical relaxation of the strong CP angle to its minimum of zero. One solution to this PQ “quality problem” is to introduce heavy QCD axions. …
