By studying singularities in stationary axisymmetric Kerr and Tomimatsu-Sato solutions with distortion parameter \d = 2, 3, ... [...] Fulltext: Download fulltextPDF Download fulltextPS.GZ;
12. Phenomenological Study of Solar-Neutrino Induced Double Beta Decay of Mo100 / Domin, P ; Simkovic, F ; Semenov, S V ; Gaponov, Y V [hep-ph/0204143]
The detection of solar-neutrinos of different origin via induced beta beta process of Mo100 is investigated. [...] Fulltext: Download fulltextPDF Download fulltextPS.GZ;
13. Fine Structure Constant Variation from a Late Phase Transition / Chacko, Z ; Grojean, C ; Perelstein, M [hep-ph/0204142]
Recent experimental data indicates that the fine structure constant alpha may be varying on cosmological time scales. [...] Fulltext: Download fulltextPDF Download fulltextPS.GZ;
14. Modular Invariant Anomalous U(1) Breaking / Gaillard, M K ; Giedt, J [LBNL-50097] [UCB-PTH-02-14] [hep-th/0204100]
We describe the effective supergravity theory present below the scale of spontaneous gauge symmetry breaking due to an anomalous U(1), obtained by integrating out tree-level interactions of massive modes. [...] Fulltext: Download fulltextPDF Download fulltextPS.GZ;
15. Neutrino Masses in Theories with Dynamical Electroweak Symmetry Breaking / Appelquist, T ; Shrock, R [hep-ph/0204141]
We address the problem of accounting for light neutrino masses in theories with dynamical electroweak symmetry breaking. [...] Fulltext: Download fulltextPDF Download fulltextPS.GZ;
16. A new model-independent way of extracting |V_ub/V_cb| / Aglietti, U ; Ciuchini, M ; Gambino, P [CERN-TH-2002-069] [RM3-TH-02-4] [hep-ph/0204140]
The ratio between the photon spectrum in B -> X_s gamma and the differential semileptonic rate wrt the hadronic variable M_X/E_X is a short-distance quantity calculable in perturbation theory and independent of the Fermi motion ofthe b quark in the B meson.

17. Remarks on the f_0(400-1200) scalar meson as the dynamically generated chiral partner of the pion / Van Beveren, E ; Kleefeld, F ; Rupp, G ; Scadron, M D [hep-ph/0204139]
The quark-level linear sigma model is revisited, in particular concerning the identification of the f_0(400-1200) (or \sigma(600)) scalar meson as the chiral partner of the pion. [...] Fulltext: Download fulltextPDF Download fulltextPS.GZ;

19. Leptogenesis with Majorana neutrinos / Paschos, E A [DO-TH-02-05] [hep-ph/0204137]
I review the origin of the lepton asymmetry which is converted to a baryon excess at the electroweak scale. [...] Fulltext: Download fulltextPDF Download fulltextPS.GZ;
20. Supersymmetry and a rationale for small CP violating phases / Branco, G C ; Gomez, M E ; Khalil, S ; Teixeira, A M [FISIST-14-2001-CFIF] [IPPP-01-58] [DCPT-01-114] [hep-ph/0204136]
We analyse the CP problem in the context of a supersymmetric extension of the standard model with universal strength of Yukawa couplings. [...] Fulltext: Download fulltextPDF Download fulltextPS.GZ;
