Universal extra dimensions and Z->b bar-b
J. F. Oliver, J. Papavassiliou, A. Santamaria
We study, at the one loop level, the dominant contributions from a single universal extra dimension to the process (Z\to b\bar{b}). By resorting to the gaugeless limit of the theor…
QCD Effective Actions at High Temperature and the Quasiparticle Picture
Cristina Manuel
Transport theory is an efficient approach to derive an effective theory for the soft modes of QCD at high temperature. It is known that the leading order operators of this theory c…
Determination of m_s and |V_us| from hadronic tau decays
E. Gamiz, M. Jamin, A. Pich +2
The mass of the strange quark is determined from SU(3)-breaking effects in the tau hadronic width. Compared to previous analyses, the contributions from scalar and pseudoscalar spe…
DIS structure functions and the double-spin asymmetry in electroproduction within a Regge approach
N. I. Kochelev, K. Lipka, W. -D. Nowak +2
The proton, neutron and deuteron structure functions and , measured at intermediate , are analyzed within a Regge approach. This analysis serves to fi…
Solar Neutrinos Before and After KamLAND
John N. Bahcall, M. C. Gonzalez-Garcia, Carlos Pena-Garay
We use the recently reported KamLAND measurements on oscillations of reactor anti-neutrinos, together with the data of previously reported solar neutrino experiments, to show that:…
Combining first KamLAND results with solar neutrino data
M. Maltoni, T. Schwetz, J. W. F. Valle
We consider the impact of the recent KamLAND data on neutrino oscillations, the first terrestrial neutrino experiment that can probe the solar neutrino anomaly. By combining the fi…
