Exclusive electroproduction of K+ Lambda and K+ Sigma^0 final states at Q^2 = 0.030-0.055 (GeV/c)^2
P. Achenbach, C. Ayerbe Gayoso, J. C. Bernauer +32
Cross section measurements of the exclusive p(e,e'K+)Lambda,Sigma^0 electroproduction reactions have been performed at the Mainz Microtron MAMI in the A1 spectrometer facility usin…
CP-odd WWZ couplings induced by vector-like quarks
Eri Asakawa, Miho Marui, Noriyuki Oshimo +2
A minimal extension of the standard model includes extra quarks with charges 2/3 and/or -1/3, whose left-handed and right-handed components are both SU(2) singlets. This model pred…
CP-odd Anomalous W-boson Couplings from Supersymmety
Minako Kitahara, Miho Marui, Noriyuki Oshimo +2
The supersymmetric standard model contains a new CP-violating phase in the mass matrices for charginos and neutralinos, which could induce CP-odd anomalous couplings for the WWZ an…
Study of CP Violation: Electroweak Baryogenesis and Anomalous W-Boson Couplings
Akio Sugamoto, Mayumi Aoki, Tomoko Kadoyoshi +5
The contributions from the Ochanomizu CP Study Group to the KEK meetings on "CP violation and its origin" (1993-1997) are summarized on electroweak baryogenesis and anomalous W-bos…
