In order to reveal the nature of dark matter,it is crucial to detect its non-gravitational interactions with the standard model particles.The traditional dark matter searches focused on the so-called weakly interacting massive particles.However,this paradigm is strongly constrained by the null results of current experiments with high precision.Therefore there is a renewed interest of searches for heavy dark matter particles above TeV scale.The Large High Altitude Air Shower Observatory (LHAASO) with large effective area and strong background rejec-tion power is very suitable to investigate the gamma-ray signals induced by dark matter annihilation or decay above TeV scale.In this document,we review the theoretical motivations and background of heavy dark matter.We re-view the prospects of searching for the gamma-ray signals resulted from dark matter in the dwarf spheroidal satel-lites and Galactic halo for LHAASO,and present the projected sensitivities.We also review the prospects of search-ing for the axion-like particles,which are a kind of well motivated light pseudo-scalars,through the LHAASO meas-urement of the very high energy gamma-ray spectra of astrophysical sources.

In the first part of this Chapter the present state of knowledge from the observations of cosmic rays between 1013 and 1020 eV is summarized.This is not intended to be a complete review,but rather a broad overview of the relevant processes involving cosmi
Extra-galactic gamma-ray sources,such as gamma-ray bursts,active galactic nuclei,starburst galaxies,are interesting and important targets for LHAASO observations.In this chapter,the prospects of detecting these sources with LHAASO and their physical impli
The proposed Circular Electron Positron Collider (CEPC) with a center-of-mass energy √s =240 GeV will primarily serve as a Higgs factory.Additionally,it will offer good opportunities to search for new physics phe-nomena at low energies,which can be challe
2020年初以来的新冠疫情应对和疫后重建工作,对中国人民的思想和生活产生了重大影响.高校思政课教师可以结合抗疫进展,深入挖掘中华优秀传统文化、革命文化和社会主义先进文化元素,充分发挥宣传舆论和思想教育的作用,探索文化自信培育的方式方法和实践路径.一是挖掘中医文化精髓引导大学生对疾病真相和中西医理性的认知;二是汲取中华优秀传统文化精华提升学生境界;三是结合革命文化和社会主义先进文化培育学生对党和人民辩证关系的价值认同.通过引导大学生3个递进层次的培育路径,对大学生树立文化自信,提升人生境界,具有非常重要的现

历史文化名城具有丰富的文化内涵和厚重的历史底蕴,不仅是我国文化遗产的重要组成部分,更是一座极具研究意义的文化资源宝库.习近平总书记指出:“历史文化是城市的灵魂,要像爱惜自己的生命一样保护好城市历史文化遗产.”沈阳作为第二批国家历史文化名城,正在向国家中心城市不断迈进,历史文化名城这张牌还不够重、不够亮.必须加强对历史文化名城建设研究,总结先进的保护与发展理念,明确城市发展定位,补齐历史文化名城建设短板,不断焕发历史文化名城的蓬勃生机与活力.通过历史文化名城建设让文化引领城市发展,使沈阳跻身国内一流城市.
