全矩阵元素计算与LHC生产的$W_R$简化计算的比较(左右对称模型)

Comparison of the full matrix element calculation with the simplified calculation of the $W_R$ production at the LHC (left-right symmetric model)

G. Bednik, M. Kirsanov

摘要:

我们估计可能出现的系统误差,可能出现在简化模拟的$W_R$生产和随后的衰变到重中微子在LHC(左右对称模型)。通用事件发生器将此过程模拟为$W_R$产生,然后是两次衰变,丢失了有关中间粒子极化的全部信息。我们使用带有传播子的全矩阵元计算了截面,进行了模拟,并与简化的模拟结果进行了比较

英文摘要:

We estimate possible systematic error that can arise in the simplified simulation of the $W_R$ production and its subsequent decay into heavy neutrino at LHC (left-right symmetric model). The general-purpose event generators simulate this process as a $W_R$ production followed by two decays, loosing full information about the polarization of the intermediate particles. We calculate the cross section using the full matrix elements with propagators, perform the simulation and compare the results with the simplified simulation
