Should governments prioritize funding for abstract fundamental physics research in their national budgets?
The Swiss National Science Foundation has awarded a grant to researchers at EPFL, Nikhef, and VU Amsterdam to investigate neutral B mesons. This project utilizes the Run 3 dataset from the LHCb experiment to probe for physics beyond the Standard Model.
Why it matters
The research seeks to solve the mystery of why matter dominates antimatter in the universe by investigating fundamental imbalances. By testing the Standard Model, scientists hope to uncover new physical laws governing the nature of existence.
The study aims to improve the precision of the CKM angle beta measurement by a factor of two to three. This research involves calibrating the scintillating-fiber tracking detector using the complete dataset from the LHCb experiment at CERN.
The players
EPFL
The Swiss Federal Institute of Technology in Lausanne is a public research university specializing in science and engineering.
Nikhef
The Dutch National Institute for Subatomic Physics coordinates and supports research in high-energy physics across the Netherlands.
CERN
The European Organization for Nuclear Research is a premier international research facility that operates the world's largest particle physics laboratory.
VU Amsterdam
Vrije Universiteit Amsterdam is a public research university located in the Netherlands that hosts extensive physics research programs.
The details
Researchers will combine measurements of various B-meson decays to gain insights into the CKM angle beta, which is critical for understanding particle behavior. The funding supports one PhD student and one postdoctoral researcher who will work across institutions in Lausanne and Amsterdam.

The Big Picture
This project continues the rigorous testing of the Standard Model of particle physics by searching for anomalies in meson decay. It shifts the focus toward identifying gaps in our current understanding of the physical forces that shaped the early universe.
While this research is theoretical, it contributes to the fundamental knowledge of how the universe is constructed at a subatomic level. Successful results could eventually lead to new discoveries in high-energy physics that reshape our understanding of physical reality.
The takeaway
Understanding the discrepancy between matter and antimatter remains one of the most challenging goals in modern physics. This project demonstrates how collaborative international efforts are essential to achieve the precision needed to unlock these cosmic secrets.
