One-loop sfermion corrections to in the MSSM
Sher Alam, Kaoru Hagiwara, Shinya Kanemura +2
We study one-loop effects of sfermions on helicity amplitudes for $\eeww$ in the Minimal Supersymmetric Standard Model. The one-loop contributions are calculated in the $\bar{\rm M…
Constraints on the mSUGRA parameter space from electroweak precision data
G. C. Cho, K. Hagiwara, C. Kao +1
We place constraints on the parameter space of the minimal supergravity (SUGRA) inspired supersymmetric (SUSY) extension of the standard model (SM), i.e. the mSUGRA model, by study…
Sum rules for helicity amplitudes from BRS invariance
Sher Alam, Kaoru Hagiwara, Shinya Kanemura +2
The BRS invariance of the electroweak gauge theory leads to relationships between amplitudes with external massive gauge bosons and amplitudes where some of these gauge bosons are…
Contributions of LEP1.5, LEP2 and linear-collider data to indirect constraints on non-Abelian gauge-boson couplings
R. Szalapski
It is possible to place direct constraints on WW-photon and WWZ couplings by studying their tree-level contributions to the process e^+e^- ---> W^+W^-. However, these couplings als…
Low-Energy Constraints on New Physics Revisited
S. Dawson, S. Alam, R. Szalapski
It is possible to place constraints on non-Standard-Model gauge-boson self-couplings and other new physics by studying their one-loop contributions to precisely measured observable…
Probing nonstandard bosonic interactions via W-boson pair production at lepton colliders
K. Hagiwara, T. Hatsukano, S. Ishihara +1
The process e+e- --> W+W- provides a valuable laboratory to test the Standard Model (SM) and to search for new physics. The most general helicity amplitudes for this process requir…
