Weakly-Interacting-Massive-Particles (WIMPs) are a large class of viable dark matter candidates. We employ heavy particle effective field theory to compute general heavy electroweak multiplets and nucleon elastic scattering up to heavy mass $1/M$ order.
For certain electroweak multiplets, leading order effective theory calculation shows a generic amplitude-level cancellation that yields a...
We discuss the axion objects such as axion mini-clusters and axion clouds around spinning
black holes, which induce parametric resonances of electromagnetic waves through the
axion-photon interaction, as well as high frequency gravitational waves through gravitational Chern-Simons (CS) coupling. We also present some new detection schemes for axions and high frequency waves.
We propose to search for a heavy neutral lepton (HNL), that is also
known as sterile neutrino, in electron colliders running
with the center-of-mass energies at few GeV, including BESIII, Belle II,
and the proposed Super Tau Charm Factory (STCF). We consider the HNL
interacting with Standard Model neutrino and photon via a transition
magnetic moment, the so-called dipole portal. We use...
中微子质量问题是粒子物理标准模型现有的重大问题之一。利用含有右手中微子的跷跷板机制可以解释该问题,同时右手中微子又可以通过轻子生成机制解释宇宙正反物质不对称,因此寻找右手中微子是一个极具吸引力的课题。然而,对撞机实验在框架下无法直接寻找到右手中微子检验跷跷板机制。我们基于模型,研究了该模型额外的右手中微子产生通道。利用其独特的长寿命粒子信号,我们进行了对撞机唯象学分析,发现在一定参数空间内,可以成功检验跷跷板机制。与此同时,额外的右手中微子产生通道在轻子生成机制中,能够产生强烈的冲刷项,大大减少产生的正反物质不对称。所以对撞机寻找该通道也能够检验轻子生成机制。
By adopting a non-relativistic (NR) reduction method, we study the one-fermion matrix elements between the fermion-gravity and the fermion-photon interactions in the presence of the minimal Lorentz-violating (LV) fermion coefficients. We prescribed the Lense-Thirring (LT) metric with the test particle assumption, as this metric is essentially curved and may demonstrate some novel LV...
The energy correlators measure the pattern of the energy deposition in detectors. The collinear limit, where the angle between the detectors approaches zero, is of particular interest for describing the substructure of jets produced at colliders. By utilizing our factorization theorem and calculating the required ingredients, we perform the resummation of the logarithmically enhanced terms for...
