Standard Model singlet neutrinos propagating in extra dimensions induce small Dirac neutrino masses. While it seems rather unlikely that their KaluzaKlein excitations directly participate in the observed neutrino oscillations, their virtual exchange may lead to detectable signatures in future neutrino experiments and in rare charged lepton processes. We show how these effects can be described by specific dimensionsix effective operators and discuss their experimental signals. 1

Phenomenological Implications of the mt RGE Fixed Point

"... In minimal SUSYGUT models with MSUSY ∼ <1 TeV, the renormalization group equations have a solution dominated by the infrared fixed point of the top Yukawa coupling. This fixed point predicts mt = (200 GeV) sin β; combined with the LEP results it excludes mt ∼ <130 GeV. For mt in the range 130 ..."

130160 GeV, we discuss the sensitivity of the mt fixed point result to GUT threshold corrections and point out the implications for Higgs boson searches. The lightest scalar h has mass 6085 GeV and will be detectable at LEPII. At SSC/LHC, each of the five scalars h, H, A, H ± may be detectable

By using a model independent Monte Carlo approach, we study the possible structure of charged and neutral lepton mass matrices, under the assumption of an U(2) horizontal symmetry (additional to the usual Standard Model ones) involving the light fermion generations. We assume the most general Majorana mass matrix for neutrinos. We update the results of our previous similar study, by inserting in the analysis the recent KamLAND data, that contributed to find a final solution to the Solar neutrino problem. The introduction of the new experimental data reduce the allowed regions in the nine dimensional space parameters, and show that our procedure gives stable solutions. 1

The soft pion theorem in the inclusive reaction at high energy applied to the current induced reaction is explained briefly. A characteristic aspect of this theorem is the charge asymmetry produced by the pole terms in the soft pion limit. The pion charge asymmetry in the central region in the targetvirtualphoton center of the mass (CM) frame of the semiinclusive electroproduction and the contribution to the Gottfried sum are illustrated as examples. 1

The generic predictions of twotexture zero neutrino mass matrices of class A in the flavor basis have been reexamined especially in relation to the degeneracy between mass matrices of types A1 and A2 and interesting constraints on the neutrino parameters have been obtained. It is shown that the octant of θ23 and the quadrant of the Diractype CPviolating phase δ can be used to lift this degeneracy. Mass matrices provide important tools for the investigation of the underlying symmetries and the resulting dynamics. The first step in this direction is the reconstruction of the neutrino mass matrix in the flavor basis. However, the reconstruction results in a large variety of possible structures of mass matrices depending strongly on the mass scale, mass hierarchy and the Majorana phases. However, the relatively weak dependence on some oscillation parameters (θ23 and δ) results in the degeneracy of possible neutrino mass matrices since all the parameters are not known at present. The mass matrix for Majorana neutrinos contains nine physical parameters including the three mass eigenvalues, three mixing angles and the three CPviolating phases. The two squaredmass differences (∆m 2 21 and ∆m2 32) and the two mixing angles (θ12 and θ23) have been measured in solar, atmospheric and reactor experiments. The third mixing angle θ13 and the Diractype CPviolating phase δ are expected to be measured in the forthcoming neutrino oscillation experiments. The possible measurement of the effective Majorana mass in neutrinoless double β decay searches will provide an additional constraint on the remaining three neutrino parameters viz. the neutrino mass scale and two Majorana CP violating phases. While the neutrino mass scale will be determined by the direct beta decay searches and cosmological observations, the two Majorana phases will not be uniquely determined even if the absolute neutrino mass scale is known. Under the circumstances, it is natural to employ other theoretical inputs

I report on some recent work done in collaboration with E. de Rafael on the connection between ultraviolet renormalons in QCD and NambuJonaLasiniolike Lagrangians as its effective description at low energies. In a superconductor [1], let us denote by V the lowest order amplitude for two electrons to scatter off each other through the exchange of a phonon (V is a negative number). We shall assume both electrons are outside but very close to the Fermi sphere and we shall approximate V to be a constant. One can see that the total amplitude for this scattering process is actually an infinite sum T ≈ V ( 1 + γV + γ 2 V 2 +...) (1) where γ ∼ κ −1 log(E/ω), with κ> 0 a constant depending on the metal, ω a parameter describing the effective interaction range (in momentum space) and E is the total energy of the electron pair. Under normal conditions γV is small and the above series can be truncated after the firstfew terms. However, when E is very small more and more terms become important and one has to consider the resummation of the series (1):
