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…
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…
Single Neutralino production at CERN LHC
G. J. Gounaris, J. Layssac, P. I. Porfyriadis +1
The common belief that the lightest supersymmetric particle (LSP) might be a neutralino, providing also the main Dark Matter (DM) component, calls for maximal detail in the study o…
Physics Interplay of the LHC and the ILC
LC Study Group, G. Weiglein, T. Barklow +120
Physics at the Large Hadron Collider (LHC) and the International e+e- Linear Collider (ILC) will be complementary in many respects, as has been demonstrated at previous generations…
