A. Caliskan

摘要:

本文分析了ERL 60 $\otimes$ FCC($\sqrt{s}=3.46$ TeV)、ILC $\otimes$ FCC($\sqrt{s}=10$ TeV)和PWFA-LC $\otimes$ FCC($\sqrt{s}=31.6$ TeV)三台FCC对撞机上激发中微子的产生势。计算了不同衰变通道的激发中微子分支比,结果表明主要的衰变通道是$ν^{\star}\rightarrow eW^{+}$。计算了$ep\rightarrowν^{\star}q\rightarrow eW^{+}q$过程的产生截面和$ν^{\star}\rightarrow eW^{+}$过程的激发中微子衰变宽度。信号和相应的背景进行了详细研究,以获得可访问的质量限制。结果表明,对于$L_{int}=100$ $fb^{-1}$,所得到的激发中微子质量的发现极限为$2452$ GeV,$5635$ GeV用于$L_{int}=10$ $fb^{-1}$($6460$ GeV用于$L_{int}=100$ $fb^{-1}$),和$10200$ GeV,用于$L_{int}=1$ $fb^{-1}$($L_{int}=10$ $fb^{-1}$的$13960$ GeV MU),分别用于$3.46$、$10$和$31.6$ TeV的质心能量。

英文摘要:

The production potential of the excited neutrinos at the FCC-based electron-hadron colliders, namely the ERL60$\otimes$FCC with $\sqrt{s}=3.46$ TeV, the ILC$\otimes$FCC with $\sqrt{s}=10$ TeV, and the PWFA-LC$\otimes$FCC with $\sqrt{s}=31.6$ TeV, has been analyzed. The branching ratios of the excited neutrinos have been calculated for the different decay channels and shown that the dominant channel is $ν^{\star}\rightarrow eW^{+}$. We have calculated the production cross sections with the process of $ep\rightarrowν^{\star}q\rightarrow eW^{+}q$ and the decay widths of the excited neutrinos with the process of $ν^{\star}\rightarrow eW^{+}$. The signals and corresponding backgrounds are studied in detail to obtain accessible mass limits. It is shown that the discovery limits obtained on the mass of the excited neutrino are $2452$ GeV for $L_{int}=100$ $fb^{-1}$, $5635$ GeV for $L_{int}=10$ $fb^{-1}$ ($6460$ GeV for $L_{int}=100$ $fb^{-1}$), and $10200$ GeV for $L_{int}=1$ $fb^{-1}$ ($13960$ GeV for $L_{int}=10$ $fb^{-1}$), for the center-of-mass energies of $3.46$, $10$, and $31.6$ TeV, respectively.
