Prospects for the Zee-Babu Model at the CERN LHC and low energy experiments

We analyze the viability of the Zee-Babu model as an explanation of observed neutrino masses and mixings and the possibility that the model is confirmed or discarded in experiments planned for the very close future. The allowed parameter space is studied analytically by using some approximations and partial data. Then, a complete scanning of all parameters and constraints is performed numerically by using Monte Carlo methods. The cleanest signal of the model will be the detection of the doubly charged scalar at the LHC and its correlation with measurements of the branching ratio of {mu}{yields}e{gamma} at the MEG experiment. In addition, the model offers interesting predictions for {tau}{sup -}{yields}{mu}{sup +}{mu}{sup -}{mu}{sup -} experiments, lepton-hadron universality tests, the {theta}{sub 13} mixing in neutrino oscillations and the {sub ee} parameter of neutrinoless double beta decay.

Noise evaluation of Compton camera imaging for proton therapy

By resorting to the gaugeless limit of the theory we explain why the result is expected to display a strong dependence on the mass of the top quark, not identified in the early literature. A detailed calculation corroborates this expectation, giving rise to a lower bound for the compactification scale which is comparable to that obtained from the

Development of a PET prototype with continuous LYSO crystals and monolithic SiPM matrices

We critically revisit the issue of power-law running in models with extra dimensions. The analysis is carried out in the context of a higher-dimensional extension of QED, with the extra dimensions compactified on a torus. It is shown that a naive

function, which simply counts the number of modes, depends crucially on the way the thresholds of the Kaluza-Klein modes are crossed. To solve these ambiguities we turn to the vacuum polarization, which, due to its special unitarity properties, guarantees the physical decoupling of the heavy modes. This latter quantity, calculated in the context of dimensional regularization, is used for connecting the low energy gauge coupling with the coupling of the
