Are the pentaquark sum rules reliable?

Ricardo D. Matheus, Stephan Narison

We rewiew and scrutinize the existing mass determinations of the pentaquarks from the exponential Laplace Sum Rules (LSR). We do not find any sum rule window for extracting optimal…

Heavy-light mesons in QCD

Stephan Narison

This talk summarizes the study of the dynamics of the heavy-light \bar Qq open charm and beauty mesons obtained in [1] using QCD spectral sum rules (QSSR) and motivated by the rece…

Split Supersymmetry at the Logarithmic Test of Future Colliders

M. Beccaria, F. M. Renard, C. Verzegnassi

We consider a large number of pair production processes at future colliders (LHC, ILC) for values of the c.m. energy in the TeV range, where a logarithmic expansion of Sudakov kind…

On the diffraction pattern of C60 peapods

Julien Cambedouzou, Vincent Pichot, Stephane Rols +5

We present detailed calculations of the diffraction pattern of a powder of bundles of C peapods. The influence of all pertinent structural parameters of the bundles on the d…

V-A hadronic tau decays : a laboratory for the QCD vacuum

Stephan Narison

ALEPH/OPAL data on the V-A spectral functions from hadronic tau decays are used in connection with a set of Laplace transform sum rules (LSR) for fixing the size of the QCD vacuum…

Cubic supersymmetry and abelian gauge invariance

G. Moultaka, M. Rausch de Traubenberg, A. Tanasa

On the basis of recent results extending non-trivially the Poincaré symmetry, we investigate the properties of bosonic multiplets including form gauge fields. Invariant free La…
