Higgs distribution in Higgs + jet production at hadron colliders within the non-commutative Higgs effective standard model
We use the non-commutative Higgs effective standard model to make a
phenomenological prediction for the transverse momentum distribution of the
Higgs boson produced in association with a jet at hadron colliders. We
calculate at leading order in the non-commutative parameter as well as
leading order in the strong coupling , the one-loop
distribution of the Higgs boson. As in the standard model, the fixed-order
distribution suffers from large logarithms at small which require an
all-orders resummation. We find that the large- region of the distribution
is strongly affected by the non-commutativity, while small- region is not.
Following this observation, we propose a simple matching method that allows us
to compute a result that is also valid at small obtained with
standard-model parton showers such as Pythia 8.Comment: 9 pages, 3 figure
Second-order corrections to the non-commutative Klein-Gordon equation with a Coulomb potential
We improve the previous study of the Klein-Gordon equation in a
non-commutative space-time as applied to the Hydrogen atom to extract the
energy levels, by considering the second-order corrections in the
non-commutativity parameter. Phenomenologically we show that non-commutativity
is the source of lamb shift corrections.Comment: 12 pages, no figure
