Neutron production from the fracture of piezoelectric rocks

A theoretical explanation is provided for the experimental evidence that fracturing piezoelectric rocks produces neutrons. The elastic energy microcrack production ultimately yields the macroscopic fracture. The mechanical energy is converted by the piezoelectric effect into electric field energy. The electric field energy decays via radio frequency (microwave) electric field oscillations.Theradiofrequency electricfields accelerate thecondensed matter electrons which then collide with protons producing neutrons and neutrinos.

Total cross-section and rapidity gap survival probability at the LHC through an eikonal with soft gluon resummation

New results are presented for total pp/pp cross sections, in the framework of our QCD based model (GGPS). This is an improved eikonal mini-jet model, where soft gluon radiation tames the fast energy rise normally present in mini-jet models. We discuss the variability in our predictions and provide a handy parametrization of our results for the LHC. We find that our model predictions span the range

Soft gluon k t -resummation and the froissart bound

mb. While this matches nicely with the range of most other models, it does not agree with recent ones which include a “hard” pomeron, even though our model does include hard scattering. We compute the survival probability for large rapidity gap (LRG) events at the LHC and at the Tevatron. These events are relevant, for example, for Higgs signal in the WW fusion process. We also explore whether measurements of the total cross sections at the LHC can help us sharpen the model parameters and hence estimates for these survival probabilities, further.

Quantum dissipation induced noncommutative geometry

Abstract The quantum theory of Brownian motion is discussed in the Schwinger version wherein the notion of a coordinate moving forward in timex(t) is replaced by two coordinates,x+(t) moving forward in time andx−(t) moving backward in time. The role of the doubling of the degrees of freedom is illustrated for the case of electron beam two slit diffraction experiments. Interference is computed with and without dissipation (described by a thermal bath). The notion of a dissipative interference phase, closely analogous to the Aharonov–Bohm magnetic field induced phase, is explored.

Checks of asymptotia in pp elastic scattering at LHC

We present a detailed study, done in the framework of the INFN 2006 Roadmap, of the prospects for e+e- physics at the Frascati National Laboratories. The physics case for an e+e- collider running at high luminosity at the phi resonance energy and also reaching a maximum center of mass energy of 2.5 GeV is discussed, together with the specific aspects of a very high luminosity tau-charm factory. Subjects connected to Kaon decay physics are not discussed here, being part of another INFN Roadmap working group. The significance of the project and the impact on INFN are also discussed. All the documentation related to the activities of the working group can be found in http://www.roma1.infn.it/people/bini/roadmap.html.
