S_3 Flavor Symmetry and Leptogenesis

open access: yes, 2005
We consider leptogenesis in a minimal S_3 extension of the standard model with an additional Z_2 symmetry in the leptonic sector. It is found that the CP phase appearing in the neutrino mixing is the same as that for the CP asymmetries responsible for ...

Stable signal recovery from incomplete and inaccurate measurements [PDF]

open access: yes, 2005
Suppose we wish to recover a vector x0 ∈ ℝ𝓂 (e.g., a digital signal or image) from incomplete and contaminated observations y = A x0 + e; A is an 𝓃 × 𝓂 matrix with far fewer rows than columns (𝓃 ≪ 𝓂) and e is an error term.

The cross section for e+e−→e+e−e+e−

open access: yesNuclear Physics B, 1984
Abstract A calculation of the cross section for the process e + e − →e + e − e + e − is presented. The complete set of 36 Feynman diagrams is taken into account and is computed at the amplitude level, neglecting the electron mass. Emphasis is placed on the requirement for any such calculation that it can be done numerically in a fast and simple way.
