论文摘要
标准型号（SM）的量子$（1）$是一个简单且无异常的框架，其中引入了三代Majorana类型的右中微子（RHNS），以通过Seesaw机制生成轻中微子的质量和风味混合。我们通过$ z^\ prime $诱导的Majorana型RHNS对生产研究了不同的强子和Lepton Colliders的此类模型。我们在u $（1）上得出界限$量表耦合$（g^\ prime）$将模型横截面与实验观察到的不同$ z^\ prime $ smos $（m_ {z^\ prime}）$和rhns smos $ $（m_n）$的实验观察到的数据进行了比较。使用这些限制，我们估算了允许的RHN对生产横截面，该横截面可以由Lepton数字违反签名与Handron Colliders在RHNS的质量上相关的签名。因此，我们以$ m_ {z^\ prime} $和$ m_n $的不同基准值的信号为fat-jet/s的Dilepton和Trilepton模式。使用脂肪喷射签名并研究信号和相应的SM背景，我们在$ m_n-m_ {z^\ prime} $平面上估算了不同的质量能量中心的范围，这些质量中心可以在不同的强子围墙处探测。在Lepton Colleders的背景下，我们考虑了电子正电子初始状态，其中Majorana型RHN可以从$ z^\ prime $中产生相同的标志Dilepton Plus Dilepton Plus Jets Signature and Trilepton Plus Trilepton Plus Jets与缺少能量的Jets。在研究信号和相应的SM背景时，我们估计$ m_n-m_ {z^\ prime} $平面在不同的质量能量中心。在u $（1）$ sm扩展的背景下，有一个SM Singlet BSM标量与RHN相连。我们可以通过电子正电子山脉的BSM标量产生来探测RHN的主要性质。
A gauged U$(1)$ extension of the Standard Model (SM) is a simple and anomaly free framework where three generations of Majorana type right-handed neutrinos (RHNs) are introduced to generate light neutrino mass and flavor mixings through the seesaw mechanism. We investigate such models at different hadron and lepton colliders via $Z^\prime$ induced Majorana type RHNs pair production. We derive bounds on U$(1)$ gauge coupling $(g^\prime)$ comparing the model cross sections with experimentally observed data for different $Z^\prime$ mass $(M_{Z^\prime})$ and RHNs mass $(M_N)$. Using these limits we estimate the allowed RHN pair production cross section which can be manifested by lepton number violating signatures in association with fat-jets at the hadron colliders depending on the mass of the RHNs. Hence we study dilepton and trilepton modes with fat-jet/s of the signal for different benchmark values of $M_{Z^\prime}$ and $M_N$. Using fat-jet signatures and studying the signal and corresponding SM backgrounds, we estimate bounds on $M_N-M_{Z^\prime}$ plane at different center of mass energies which could be probed at different hadron colliders. In the context of the lepton colliders we consider electron positron initial states where Majorana type RHNs can be produced from $Z^\prime$ manifesting same sign dilepton plus jets signature and trilepton plus jets in association with missing energy. Studying the signal and corresponding SM backgrounds we estimate the bounds on the $M_N-M_{Z^\prime}$ plane for different center of mass energies. In the context of U$(1)$ extension of the SM there is an SM singlet BSM scalar which couples with the RHNs. We can probe the Majorana nature of RHNs via this BSM scalar production at electron positron colliders.
