The Gamma-count distribution in the analysis of experimental underdispersed data
Walmes Marques Zeviani, Paulo Justiniano Ribeiro, Wagner Hugo Bonat +2
Event counts are response variables with non-negative integer values representing the number of times that an event occurs within a fixed domain such as a time interval, a geograph…
The full electroweak Standard Model prediction for (g-2) of the muon and improvements on the MSSM prediction
H. G. Fargnoli, C. Gnendiger, S. Passehr +2
Recent progress on the (g-2)_μprediction is presented. In the SM, the Higgs-boson mass dependent contributions have been evaluated exactly up to the two-loop level and consistently…
Two-Loop Corrections to the Muon Magnetic Moment from Fermion/Sfermion Loops in the MSSM: Detailed Results
Helvecio Fargnoli, Christoph Gnendiger, Sebastian Paßehr +2
Recently, first results were presented for two-loop corrections to the muon (g-2) from fermion/sfermion loops in the MSSM. These corrections were shown to be generally large and ev…
From scale properties of physical amplitudes to a predictive formulation of the Nambu-Jona-Lasinio model
O. A. Battistel, G. Dallabona
The predictive power of the NJL model is considered in the light of a novel strategy to handle the divergences typical of perturbative calculations. The referred calculational stra…
Magnetization process, bipartite entanglement and enhanced magnetocaloric effect of the exactly solved spin-1/2 Ising-Heisenberg tetrahedral chain
Jozef Strecka, Onofre Rojas, Taras Verkholyak +1
The frustrated spin-1/2 Ising-Heisenberg ladder with Heisenberg intra-rung and Ising inter-rung interactions is exactly solved in a longitudinal magnetic field by taking advantage…
Non-decoupling two-loop corrections to (g-2)_μ from fermion/sfermion loops in the MSSM
Helvecio Fargnoli, Christoph Gnendiger, Sebastian Passehr +2
Two-loop contributions to the muon (g-2) from fermion/sfermion loops in the MSSM are presented, and an overview of the full MSSM prediction for (g-2) is given with emphasis on the…
