Probing neutrinoless double-beta decay by nuclear observables
Neutrinoless double-beta (0νββ) decay is a hypothetical nuclear decay in which two nucleons inside the nucleus beta-decay simultaneously emitting only two beta-particles without the associated (anti-)neutrinos. The process violates lepton-number conservation and requires that neutrinos are their own antiparticles (or Majorana particles), and observation of the decay would hence have implications in the understanding of the matter-antimatter asymmetry of the Universe. Measuring 0νββ decay is also one of the most robust probes for the absolute masses of neutrinos as its decay rate is proportional to the square of so-called effective Majorana mass. While the experiments hunting for this decay are approaching ton scales, the required nuclear-theory input remains a major obstacle to planning and interpreting the experiments. In this talk, I will cover recent nuclear-theory advances in the study of 0νββ decay and how they impact the interpretation of recent and future experiments. I will also discuss different ways to improve the nuclear-theory predictions for 0νββ decay by using experimental data on other nuclear processes that can be or have been measured.

The Breakthrough Prize in Fundamental Physics has been awarded to more than 13,000 Researchers from ATLAS, CMS, ALICE and LHCb Experiments at CERN.
For detailed measurements of Higgs boson properties confirming the symmetry-breaking mechanism of mass generation,
the discovery of new strongly interacting particles, the study of rare processes and matter-antimatter asymmetry,
and the exploration of nature at the shortest distances and most extreme conditions at CERN’s Large Hadron Collider.
The prize is for the LHC experiments, of which we have a big UCL group on ATLAS. See

It is with great sadness that we wish to inform you that Professor Basil Hiley passed
away peacefully on Saturday the 25th of January at the age of 89.
He will be remembered by many as a great physicist, one who was always willing to
follow his intuition while backing up his ideas with a phenomenal knowledge and
insight in to physics. He was also a hugely generous person, keen to share his ideas
and collaborate with many of us in the department - young and old alike.
In January 2025, UCL's President and Provost, Dr Michael Spence, visited CERN,
alongside a UCL delegation for an in-depth look at some of the world's most groundbreaking scientific advancements,
and to explore opportunities for strengthening the UCL-CERN collaborations.
New results from the LUX-ZEPLIN (LZ) collaboration involving UCL researchers have put the best-ever limits on weakly interacting massive particles (WIMPs), a leading candidate for what makes up our universe’s invisible mass.
