New LEP bounds on B-violating scalar couplings: r-parity violating supersymmetry or diquarks

We use the precision electroweak data at LEP to place bounds on B-violating Yukawa couplings, two theoretically appealing examples being provided by R-parity--violating supersymmetry and diquarks. The couplings involving the third generation quarks are most severely constrained. These bounds are com...

description We use the precision electroweak data at LEP to place bounds on B-violating Yukawa couplings, two theoretically appealing examples being provided by R-parity--violating supersymmetry and diquarks. The couplings involving the third generation quarks are most severely constrained. These bounds are complementary to those obtained from low-energy processes.
