The curvature of as a probe of the range of validity of perturbative QCD evolutions in the small- region
M. Glück, C. Pisano, E. Reya
Perturbative NLO and NNLO QCD evolutions of parton distributions are studied, in particular in the (very) small- region, where they are in very good agreement with all recent pr…
Neutrino Phenomenology, Dark Energy and Leptogenesis from pseudo-Nambu-Goldstone Bosons
C. T. Hill, I. Mocioiu, E. A. Paschos +1
We consider a model of dynamical neutrino masses via the see-saw mechanism. Nambu-Goldstone bosons (majorons) arise associated with the formation of the heavy right-handed majorana…
Neutrino Masses and Interactions in a Model with Nambu-Goldstone Bosons
E. A. Paschos
A natural scenario for the generation of neutrino masses is the see-saw mechanism, in which a large right-handed neutrino mass makes the left-handed neutrinos light. We review a sp…
Probing Lepton Number Violating Interactions with Beta-beams
Sanjib Kumar Agarwalla, Subhendu Rakshit, Amitava Raychaudhuri
We show that a detector placed near a beta-beam storage ring can probe lepton number violating interactions, as predicted by supersymmetric theories with R-parity non-conservation.…
Parton evolution in the fixed flavor factorization scheme
M. Glück, E. Reya
It is argued that while the scale dependence of the parton distributions in the fixed flavor factorization scheme is governed by three active flavors, the scale dependence of the r…
Quark-hadron duality in neutrino scattering
O. Lalakulich, W. Melnitchouk, E. A. Paschos
We present a phenomenological model of the quark-hadron transition in neutrino-nucleon scattering. Using recently extracted weak nucleon transition form factors, we investigate the…
