We discuss a particularly symmetric model of neutrino mixings where, with good accuracy, the atmospheric mixing angle Î¸23 is maximal, Î¸13 = 0 and the solar angle satisfies sin Î¸12 = 1 3â€¦ (More)

We present a small x resummation for the GLAP anomalous dimension and its corresponding dual BFKL kernel, which includes all the available perturbative information and nonperturbative constraints.â€¦ (More)

We formulate and discuss a 4-dimensional SUSY version of an A4 model for tribimaximal neutrino mixing which is completely natural. We also study the next-tothe-leading corrections and show that theyâ€¦ (More)

We provide an assessment of the impact of parton distributio ns on the determination of LHC processes, and of the accuracy with which parto n distributions (PDFs) can be extracted from data, inâ€¦ (More)

We extend our previous results on smallx resummation in the pure Yangâ€“Mills theory to full QCD with nf quark flavours, with a resummed two-by-two matrix of resummed quark and gluon splittingâ€¦ (More)

We discuss the special class of models where nearly maximal neutrino mixing is produced through the seesaw mechanism, starting from only nearly diagonal matrices for charged leptons, Dirac neutrinosâ€¦ (More)
