标题： Indications on the Mass of the Lightest Electroweak Baryon

摘要： 一般来说，复合电弱对称性破缺的有效低能拉格朗日模型包含孤子解，这些解可能被识别为技术重子。 我们回顾这类态的质量如何与有效拉格朗日量中四阶项的系数相关联，并回顾这一方法在QCD中对重子的定性成功。 然后我们展示如何利用电弱理论中相应四阶系数的当前理论和现象学约束，来估计最轻电弱重子质量的定性下限和上限。 我们还讨论了大型强子对撞机实验的灵敏度如何有助于改进这些限制。 显示英文摘要

摘要： In general, an effective low-energy Lagrangian model of composite electroweak symmetry breaking contains soliton solutions that may be identified with technibaryons. We recall how the masses of such states may be related to the coefficients of fourth-order terms in the effective Lagrangian, and review the qualitative success of this approach for baryons in QCD. We then show how the current theoretical and phenomenological constraints on the corresponding fourth-order coefficients in the electroweak theory could be used to estimate qualitative lower and upper bounds on the lightest electroweak baryon mass. We also discuss how the sensitivity of the LHC experiments could enable these bounds to be improved.
