Searching Scalar Resonances with Ultra-high Energy Neutrinos
Lars Brücher, Petteri Keränen, Jukka Maalampi
We study the prospects of detecting signals of a resonant scattering of high-energy cosmic neutrinos on electrons in the atmosphere. Such a process is possible through an s-channel…
Electroweak Corrections to the Top Quark Decay
S. M. Oliveira, L. Bruecher, R. Santos +1
We have calculated the one-loop electroweak corrections to the decay t-> bW+, including the counterterm for the CKM matrix elements V(tb). Previous calculations used an incorrect d…
Renormalization of the Cabibbo-Kobayashi-Maskawa Matrix
A. Barroso, L. Brucher, R. Santos
Using the on-shell scheme and the general linear R_xi gauge we have calculated the one-loop amplitude W+ -> u_I d_j. In agreement with previous work we have shown that the Cabibbo-…
A new Method for computing One-Loop Integrals
Lars Brucher, Johannes Franzkowski
We present a new program package for calculating one-loop Feynman integrals, based on a new method avoiding Feynman parametrization and the contraction due to Passarino and Veltman…
Automatic Feynman diagram calculation with xloops--a short overview
Lars Brucher
xloops is a program package that calculates Feynman diagrams by using computer algebra systems. In this paper it is shown which problems to be solved by computer algebra arise duri…
Experimental signature of a fermiophobic Higgs boson
Lars Brucher, Rui Santos
The most general Two Higgs Doublet Model potential without explicit CP violation depends on 10 real independent parameters . Excluding spontaneous CP violation results in two 7 par…
