Symmetries of field theories on the non-commutative plane
P. A. Horvathy, L. Martina, P. C. Stichel
New developments on the symmetries of non-relativistic field theoretical models on the non commutative plane are reviewed. It is shown in particular that Galilean invariance strong…
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…
Special Supersymmetric features of large invariant mass unpolarized and polarized top-antitop production at LHC
M. Beccaria, S. Bentvelsen, M. Cobal +2
We consider the top-antitop invariant mass distributions for production of unpolarized and polarized top quark pairs at LHC, in the theoretical framework of the MSSM. Assuming a "m…
Study of dynamical supersymmetry breaking for the two dimensional lattice Wess-Zumino model
M. Beccaria, G. F. De Angelis, M. Campostrini +1
A new approach to the study of the transition point in a class of two dimensional Wess-Zumino models is presented. The method is based on the calculation of rigorous lower bounds o…
Enlarged Galilean symmetry of anyons and the Hall effect
P. A. Horvathy, L. Martina, P. Stichel
Enlarged planar Galilean symmetry, built of both space-time and field variables and also incorporating the ``exotic'' central extension is introduced. It is used to describe non-re…
Probing supernova shock waves and neutrino flavor transitions in next-generation water-Cherenkov detectors
G. L. Fogli, E. Lisi, A. Mirizzi +1
Several current projects aim at building a large water-Cherenkov detector, with a fiducial volume about 20 times larger than in the current Super-Kamiokande experiment. These proje…
