LEP- and low energy-bounds on R-parity-violating supersymmetric Yukawa couplings

Gautam Bhattacharyya

Electroweak precision data at LEP are used to place bounds on some ${\lambda }^{\prime }$-type ($L$-violating) and ${\lambda }^{\prime \prime }$-type ($B$-violating) $R$-parity violating supersymmetric Yukawa couplings. We…
