2025年北京粒子物理与宇宙学：早期宇宙、引力波模板、对撞机唯象研讨会 （BPCS 2025）
早期宇宙天然和基础物理特别是粒子物理过程相联系，其中许多过程，诸如宇宙学一阶相变等，将会产生可观测的随机引力波背景，对各种随机引力波背景的建模将直接影响到对早期宇宙基础物理信息的提取。对基本粒子物理过程更加传统的研究方法来自对撞机及其唯象研究，近年来对于有效场论的研究极大丰富了利用对撞机唯象研究提取超出粒子物理标准模型新物理的前景。
鉴于当前对早期宇宙、引力波模板以及对撞机唯象研究的快速发展以及粒子物理和宇宙学的深度融合和交叉发展，由中国科学院理论物理研究所主办，上海交通大学李政道研究所、重庆大学、中国科学院大学国际理论物理中心（亚太地区）、电子科技大学、中国科学院高能物理研究所、北京大学高能物理中心、清华大学协办，将于2025年09月25日（报到）-09月29日（离会）在北京春晖园温泉度假酒店（政府采购酒店[央采]，北京市顺义区高泗路于庄段37号）举办 “2025年北京粒子物理与宇宙学：早期宇宙、引力波模板、对撞机唯象研讨会”。会议受到科技部重点研发计划项目资助。
本次会议也是传承自以下会议的系列会议，主要聚焦于粒子物理和宇宙学的交叉融合方向，每年将会轮换不同的主题集中研讨。
今年，我们将关注早期宇宙（宇宙学对撞机、宇宙学电弱/QCD等一阶相变、重子生成机制、暗物质产生机制、原初黑洞等）、引力波模板（早期宇宙各种基础物理过程产生的随机引力波背景等）和对撞机唯象（标准模型精确测量、新物理限制、有效场论等），进行理论、唯象、实验方面的深度讨论，促进新的想法和合作。我们诚挚邀请相关领域的专家学者以及青年科研人员莅临指导和交流！
本次研讨会将以线下报告为主，部分报告将以线上方式进行，除了邀请报告以外，还将接受提交报告，所有会议报告建议以英文方式交流。

The 2025 Beijing Particle Physics and Cosmology Symposium (BPCS 2025): early Universe, gravitational-wave templates, collider phenomenology
The early universe is inherently linked to fundamental physics, particularly particle physics processes. Many of these processes, such as the cosmological first-order phase transition, will generate observable stochastic gravitational wave backgrounds. Modeling various stochastic gravitational wave backgrounds will directly impact the extraction of fundamental physical information about the early universe. More traditional approach for fundamental particle physics processes comes from colliders and their phenomenological studies. In recent years, research on effective field theory has greatly enriched the prospects for extracting new physics beyond the Standard Model of particle physics through collider phenomenological studies.
Given the rapid development of research on the early universe, gravitational wave templates, and collider phenomenology, as well as the deep connection and cross-development of particle physics and cosmology, Institute of Theoretical Physics of the Chinese Academy of Sciences, in collaboration with Tsung Dao Lee Institute of Shanghai Jiao Tong University, Chongqing University, The International Centre for Theoretical Physics Asia-Pacific (ICTP-AP) of the University of Chinese Academy of Sciences, University of Electronic Science and Technology of China, Institute of High Energy Physics of the Chinese Academy of Sciences, High Energy Physics Center of Peking University, and Tsinghua University, will hold a conference from September 25 (registration) to September 29 (departure) at the Chun Hui Yuan Hot Spring Resort Hotel in Beijing (a government-procured hotel [central procurement], No. 37, Yuzhuang Section, Gaoshi Road, Shunyi District, Beijing), on the topics of “Early Universe, Gravitational Wave Templates, and Collider Phenomenology” The conference is supported by the National Key Research and Development Program from the Ministry of Science and Technology of China.
This conference is part of a series of conferences that build on previous events, focusing on the interdisciplinary integration of particle physics and cosmology. Each year, the conference will rotate through different themes for in-depth discussion.
This year, we will focus on the early Universe (cosmological collider, cosmological [electroweak/QCD/...] first-order phase transition, baryogenesis, dark matter production, primordial black hole, etc.), gravitational-wave templates (all kinds of stochastic gravitational wave backgrounds from early-Universe fundamental physical processes), and collider phenomenology (Standard Model precision measurements, new-physics constraints, effective field theory, etc.), engaging in in-depth discussions across theoretical, phenomenological, and experimental aspects to foster new ideas and collaborations.We sincerely invite experts and young researchers in related fields to attend and engage in guidance and exchange!
This symposium will primarily feature in-person presentations, with some sessions conducted online. In addition to invited talks, we will also accept submitted presentations. All conference presentations are recommended to be delivered in English.
