Abstract

We study the spectra of heavy-light and heavy-heavy mesons containing charm quarks, including higher spin states. We use two sets of $N_f = 2 + 1$ gauge configurations, one set from QCDSF using the SLiNC action, and the other configurations from the Budapest-Marseille-Wuppertal collaboration, using the HEX smeared clover action. To extract information about the excited states, we choose a suitable basis of operators to implement the variational method., 7 pages, 5 figures, Talk presented at the XXIX International Symposium on Lattice Field Theory, Lattice2011, July 11-16, 2011, The Village at Squaw Valley, California, USA

3. Species Doublers as Super Multiplet Partners in Lattice Supersymmetry

Abstract

We propose a new lattice superfield formalism in momentum representation which accommodates species doublers of the lattice fermions and their bosonic counterparts as super multiplets. We explicitly show that one dimensional $N=2$ model with interactions has exact supersymmetry on the lattice for all super charges with lattice momentum. In coordinate representation the finite difference operator is made to satisfy Leibnitz rule by introducing a non local product, the "star" product, and the exact lattice supersymmetry is realized. Supersymmetric Ward identities are shown to be satisfied at one loop level., 14 pages

4. Twisted Supersymmetry on a Lattice

Abstract

We construct a lattice supersymmetric model which is invariant under all supercharges of the twisted supersymmetry algebra. We introduce a mild non-commutativity on each supercharges to realize exact supersymmetry consistent with the Leibniz rule on the lattice and also formulate twisted non-commutative superspace with which the construction of super invariant action on the lattice makes manifest. As one of the first examples of explicit models on the lattice, we present super BF model in two dimensions which possesses exact twisted supersymmetry on the lattice. [Copyright &y& Elsevier]

5. Dirac-Kahler fermion with noncommutative differential forms on a lattice

Abstract

Noncommutativity between a differential form and a function allows us to define differential operator satisfying Leibniz's rule on a lattice. We propose a new associative Clifford product defined on the lattice by introducing the noncommutative differential forms. We show that this Clifford product naturally leads to the Dirac-Ka¨hler fermion on the lattice. [Copyright &y& Elsevier]
