利用OPAL探测器在LEP收集的积分光度约为614 pb− 1的数据样本，在189 GeV和209 GeV之间的质心能量下，对成对产生的双电荷希格斯玻色子进行了搜索。没有观察到信号的证据。在95%的置信水平下，双荷希格斯粒子的质量极限为98.5GeV/c2。这是第一次在质心能量大于91 GeV的情况下寻找双电荷希格斯玻色子。
A search for pair-produced doubly charged Higgs bosons has been performed using data samples corresponding to an integrated luminosity of about 614 pb−1collected with the OPAL detector at LEP at centre-of-mass energies between 189 GeV and 209 GeV. No evidence for a signal has been observed. A mass limit of 98.5 GeV/c2at the 95% confidence level has been set for the doubly charged Higgs particle in left–right symmetric models. This is the first search for doubly charged Higgs bosons at centre-of-mass energies larger than 91 GeV.
