Peking University, November 28, 2024: At the European Organization for Nuclear Research (CERN) in Geneva, Switzerland, Zhou Chen, an assistant professor at Peking University's School of Physics, collaborates with over 10,000 scientists from 110 countries to uncover the fundamental laws of the universe. A leading researcher in particle physics, Zhou is advancing our understanding of the Higgs boson through experiments at CERN’s Large Hadron Collider (LHC). His contributions highlight the rising influence of Chinese scientists globally.

Dedication to Higgs Physics Research  

The Higgs boson, theorized in 1964, holds a critical role in particle physics as it explains the origin of mass for elementary particles. Its discovery in 2012 by CERN's ATLAS and CMS experiments validated the standard model of particle physics.

Zhou began contributing to the ATLAS experiment in 2011. In 2018, he led a study observing the joint production of Higgs particles and the top quark— a milestone in particle physics. In 2023, now part of the CMS experiment, Zhou and his team achieved another breakthrough: obtaining the first direct evidence of Higgs particles decaying into Z bosons and photons. Zhou is not only a core member of the CERN research team, he also holds international academic leadership positions such as convenor of the LHC Higgs Working Group, exemplifying the growing influence of Chinese scientists in global research collaborations. 

From Passion to Scientific Mission  

Zhou’s fascination with particle physics began during his teenage years while preparing for physics competitions. After enrolling in Peking University’s School of Physics in 2006, he encountered innovative discussions on CERN’s LHC, further igniting his passion.  

In 2010, Zhou pursued a Doctor of Philosophy at Duke University, and joined CERN’s ATLAS experiment in 2013. Standing where the Higgs boson was discovered, Zhou experienced a profound shift in roles — from an observer to an active contributor. He recalled, “This change in roles made me feel not just passion but also responsibility, driving my determination to make meaningful contributions in Higgs particle research.”

Persistence and Growth Under Pressure  
In 2018, Zhou faced immense pressure when his team was tasked with completing three months’ worth of work in just one month. Operating on minimal sleep, Zhou fully committed himself and succeeded. He reflected, “That period was exhausting, but the pure joy of being fully immersed and focused remains unforgettable.” This experience became a source of resilience, bolstering his confidence in the face of future challenges.  

Teaching and Mentorship  

In 2021, Zhou returned to Peking University and established his own research group focusing on Higgs physics, mentoring numerous postdoctoral fellows, graduate students, and undergraduates to foster a culture of curiosity and initiative.  

He acknowledges that he is still honing his mentorship skills, and hopes to engage more deeply with his students to foster independent research and provide practical academic support.

From Participant to Navigator  

Beyond Higgs physics, Zhou is pioneering research in Muon physics and aims to promote localised experimental projects. He envisions Chinese scientists transitioning from participants to leaders in global collaborations.

Encouraged by China’s growing investment in basic research, Zhou anticipates more Peking University students engaging in particle physics.“If you have a deep love for science, hold on a little longer,” he advised. “What seems difficult at first may become easier as you persist, and opportunities often arise when you least expect them.”

Looking ahead, Zhou Chen’s journey exemplifies a new era for Chinese physicists, paving the way for groundbreaking discoveries that will inspire generations.
