在LHC上通过手性玻色子的独特新签名进行手性玻色子搜索的建议

Proposal for chiral bosons search at LHC via their unique new signature

M. V. Chizhov, V. A. Bednyakov, J. A. Budagov

摘要:

新的手征自旋-1玻色子的共振生产和他们的检测通过Drell-Yan过程在欧洲核子研究中心的LHC被认为是。在CalcHEP软件包中对手性玻色子生产的各种微分截面进行了定量评价。新的中性手征玻色子在不变的双轻子质量分布中可以作为Breit-Wigner共振峰观察到。然而,手性玻色子存在独特的新签名。首先,轻子横动量分布中没有雅可比峰。第二,当轻子对的峰上不变质量较高时,在柯林斯-索珀框架中的轻子角分布呈燕尾形。

英文摘要:

The resonance production of new chiral spin-1 bosons and their detection through the Drell--Yan process at the CERN LHC is considered. Quantitative evaluations of various differential cross-sections of the chiral bosons production are made within the CalcHEP package. The new neutral chiral bosons can be observed as a Breit--Wigner resonance peak in the invariant dilepton mass distribution, as usual. However, unique new signatures of the chiral bosons exist. First, there is no Jacobian peak in the lepton transverse momentum distribution. Second, the lepton angular distribution in the Collins-Soper frame for the high on-peak invariant masses of the lepton pairs has a peculiar "swallowtail" shape.
