The Coupling of Shape Dynamics to Matter
Full text linkShape Dynamics (SD) is a theory dynamically equivalent to vacuum General
Relativity (GR), which has a different set of symmetries. It trades refoliation
invariance, present in GR, for local 3-dimensional conformal invariance. This
contribution to the Loops 11 conference addresses one of the more urgent
questions regarding the equivalence: is it possible to incorporate normal
matter in the new framework? The answer is yes, in certain regimes. We present
general criteria for coupling and apply it to a few examples.The outcome
presents bounds and conditions on scalar densities (such as the Higgs potential
and the cosmological constant) not present in GR.Comment: 4 pages. Contribution to Loops '11 conference in Madrid, to appear in

The Research of Thomas P. Branson
Get PDFThe Midwest Geometry Conference 2007 was devoted to the substantial
mathematical legacy of Thomas P. Branson who passed away unexpectedly the
previous year. This contribution to the Proceedings briefly introduces this
legacy. We also take the opportunity of recording his bibliography. Thomas
Branson was on the Editorial Board of SIGMA and we are pleased that SIGMA is
able to publish the Proceedings.Comment: This is a contribution to the Proceedings of the 2007 Midwest
Geometry Conference in honor of Thomas P. Branson, published in SIGMA

Meson-baryon interaction in the meson exchange picture
Full text linkThis is the contribution to the proceedings of the MENU 2010 conference. The
recent work of Ref. [7] is summarized. Elastic piN scattering and the reaction
pi^+ p --> K^+ Sigma^+ are described simultaneously in a unitary
coupled-channels approach which respects analyticity. SU(3) flavor symmetry is
used to relate the t- and u- channel exchanges that drive the meson-baryon
interaction in the different channels. Angular distributions, polarizations,
and spin-rotation parameters are compared with available experimental data. The
pole structure of the amplitudes is extracted from the analytic continuation.Comment: 4 pages, contribution to the proceedings of the MENU 2010 conference,

On M-9-branes and their dimensional reductions
Get PDFThe M-9-brane Wess-Zumino action is constructed, and by using it, consistency
of the relation of p-branes for , suggested on the basis of
