We consider the standard model on a non-commutative space and expand the action in the
non-commutativity parameter θ^μν. No new particles are introduced; the structure group is …

We derive noncommutative multiparticle quantum mechanics from noncommutative
quantum field theory in the nonrelativistic limit. Particles of opposite charges are found to …

A non-commutative version of the usual electro-weak theory is constructed. We discuss how
to overcome the two major problems:(1) although we can have non-commutative U …

Noncommutative geometry provides a powerful tool for regularizing quantum field theories
in the form of fuzzy physics. Fuzzy physics maintains symmetries, has no fermion-doubling …

A bstract We construct actions for four dimensional noncommutative Yang-Mills theory with
star-gauge symmetry, with non-constant noncommutativity, to all orders in the …

In a recent string theory motivated paper, Nicolini, Smailagic and Spallucci (NSS) presented
an interesting model for a noncommutative inspired, Schwarzschild-like black hole solution …

Research during the last decade demonstrates that effects originating on the Planck scale
are currently being tested in multiple observational contexts. In this review we discuss …

We give a pedagogical introduction to L∞-algebras and their uses in organising the
symmetries and dynamics of classical field theories, as well as of the conventional …

There has been disagreement in the literature on whether the hydrogen atom spectrum
receives any tree-level correction due to non-commutativity. Here we shall clarify this issue …

A bstract The persistence of the hierarchy problem points to a violation of effective field
theory expectations. A compelling possibility is that this results from a physical breakdown of …
