第4届粒子物理、天体物理和宇宙学前沿国际学术研讨会
将于 2026 年 4 月 17 日至 4 月 21 日在成都电子科大举办
English Version Follows
前所未有的高能对撞数据、更高精度的粒子物理测量以及不断升级的暗物质、宇宙学与天文观测，正推动粒子物理、天文与宇宙学进入深度交叉融合的新阶段，持续催生检验标准模型与探索新物理的前沿课题。中微子振荡与暗物质等超出标准模型的关键现象，与天文和宇宙学密切相关；引力波与超高能中微子观测则开启了多信使天文学的新窗口，为理解早期宇宙的极端物理过程提供了全新探针。
本次会议为期四天，将搭建相关领域专家学者的高水平交流平台，围绕味物理、中微子、暗物质、天体粒子物理、宇宙学与引力波观测等主题，系统梳理国内外最新理论与实验进展，深入讨论未来可能的发展方向，推动我国在粒子-天体-宇宙学交叉前沿领域的持续发展。
同时，我们还计划引入：（i）强耦合新物理专题特别分会；（ii）强耦合新物理国际合作网络发起会，以推动强耦合新物理与QCD及强相互作用相变等领域的交叉合作，形成长期、稳定的国际协作机制。本次会议除口头报告外，还将提供海报展示的机会，欢迎大家提交口头报告和海报摘要，并积极参会。

The 4th Topics of Particle, Astro and Cosmo Frontiers (TOPAC 2026)
Will be held at the University of Electronic Science and Technology of China (UESTC), Chengdu, from April 17 to April 21, 2026.
Unprecedented high-energy collider data, increasingly precise particle-physics measurements, and rapidly advancing observations in astronomy, cosmology, and gravitational waves are ushering in a new era of deep synergy among particle physics, astrophysics, and cosmology, continuously generating frontier topics for testing the Standard Model and exploring new physics. Neutrino oscillations and dark matter particles, as key beyond-Standard-Model phenomena, are closely connected to astrophysics and cosmology; meanwhile, observations of gravitational waves and ultra-high-energy neutrinos are opening a window to multi-messenger astronomy, providing entirely new probes of extreme physical processes in the early Universe.
This four-day meeting will provide a platform for experts to exchange ideas across multiple themes, including flavor physics, neutrinos, dark matter, astrophysics, cosmology, and gravitational waves, to systematically review the latest theoretical and experimental progress worldwide, discuss possible future directions, and promote sustained development of this interdisciplinary frontier in China.
In addition, we plan to introduce (i) a dedicated special session on strongly coupled new physics, and (ii) an “Initiation Meeting” to launch an international collaboration network on strongly coupled new physics, aiming to foster cross-disciplinary collaboration with QCD and strong-interaction phase transitions and to establish a long-term, stable international collaboration mechanism. Besides oral presentations, the conference will also provide opportunities for poster sessions. We warmly welcome submissions of abstracts for oral and poster presentations and encourage active participation.
