LHCb brings leptons into line（图）
大型强子对撞机 轻子 正轨
2023/5/26
Today the international LHCb collaboration at the Large Hadron Collider (LHC) presented new measurements of rare particle transformations, or decays, that provide one of the highest-precision tests ye...
2017年11月30日下午2：00，应物理科学与技术学院（理论物理研究所）武雷教授邀请，上海交通大学何小刚教授来我院讲学。何教授做了题为“Flavor Physics With Higgs and Leptons”的精彩的学术报告。报告由物科院物理学省重点学科带头人肖振军教授主持，理论物理、粒子物理与核物理等相关学科教师及研究生同学约40人参加。何教授从粒子物理的标准模型出发，介绍了这一粒子物理学...

Running coupling in electroweak interactions of leptons from f(R)-gravity with torsion
Running coupling electroweak interactions leptons f(R)-gravity with torsion
2012/2/23
The f(R)-gravitational theory with torsion is considered for one family of leptons; it is found that the torsion tensor gives rise to interactions having the structure of the weak forces while the int...
A Model Independent Method to Study Dark Matter induced Leptons and Gamma rays
A Model Independent Method to Study Dark Matter induced Leptons and Gamma rays
2011/10/17
We propose a novel method to directly determine dark matter induced electron/positron spectrum at the source from experimental measurements at the earth, without reference to specific particle physics...
Mass matrices of twice four families of quarks and leptons, scalars and gauge fields as predicted by the ''spin-charge-family-theory''
Mass matrices scalars spin-charge-family-theory
2010/12/27
The theory unifying spin and charges and predicting families, proposed as a new way to explain the assumptions of the standard model of the electroweak and colour interactions, predicts at the low ene...
We consider a geometric approach to field theory in which torsion is present beside gravity and also electrodynamics for the matter field equations, and we develop the consequences of the torsion-spi...
Discovering the constrained NMSSM with tau leptons at the LHC
constrained NMSSM tau leptons
2011/1/5
The constrained Next-to-Minimal Supersymmetric Standard Model (cNMSSM) with mSugra-like boundary conditions at the GUT scale implies a singlino-like LSP with a mass just a few GeV below a stau NLSP. H...
General analysis of signals with two leptons and missing energy at the Large Hadron Collider
General analysis of signals two leptons and missing energy
2011/1/6
A signal of two leptons and missing energy is challenging to analyze at the Large Hadron Collider (LHC) since it offers only few kinematical handles.
Masses of Charged Leptons and Gauge Mixing Parameters
Charged lepton masses mixing parameters Gauge models
2010/4/9
It is shown that the electroweak physics of the electron and the muon is based on the left-right gauge model with the mixing parameters 0.2254 and 0.2746. These mixing parameters are determined by the...
