Antihydrogen: check! GBAR completes key step in antimatter research
Positrons: in their cloud. Antiprotons: generated. Deceleration: achieved. Mixing: check! The antimatter experiment GBAR has just published a paper in which it reports on their first detected antihydrogen atoms. This is a key step towards the ultimate goal of antimatter research: finding a reason for the asymmetry between matter and antimatter.

New flavour for Basel
Today we would like you to meet one of the University of Basel’s latest additions in the sciences: tenure-track Assistant Professor Admir Greljo. He joined the university’s physics department in spring and has brought lots of plans and ideas in his luggage. Find out how a childhood in a war influenced his career and how he hopes to solve the mystery of the different flavours in particle physics …

Order through kaons
The inventory of Swiss particle physics has just opened a new register for a new kind of research: thanks to EPFL assistant professor Radoslav Marchevski, it can add kaon physics to its list. The Bulgarian scientist, who did his undergraduate studies in Sofia, Bulgaria and his graduate studies in Mainz, Germany, joined the ranks of Swiss academia at the beginning of the year and brought his specialty particle with him.

First sighting of neutrinos from a collider collision
It’s a first in the world of physics: the FASER and SND@LHC experiments at CERN have seen first ever confirmed evidence of a neutrino produced in a particle collision at a collider. Both experiments specialise in weakly interacting particles to look for as yet unknown physics phenomena, and scientists hope that this new result will ultimately lead to a better understanding of neutrinos themselves, and with that to a range of open questions in particle physics.

“Strange animals” in the spotlight
When protons or ions collide with targets or each other, they produce lots of new particles. Some of these are wanted, some are unwanted, but whatever their desired status – they need to be well understood. Neutrons, which belong to these products, are a particular challenge. Their characteristics such as their energy, direction and number are a pain to measure, but knowing them well brings many advantages to various branches of science and its applications. A novel experimental approach based on a new neutron spectrometer recently tested by members of the Laboratory for High-Energy Physics at the University of Bern in collaboration with Politecnico di Milano and its spin-off company Raylab yields promising results that appear to be even more versatile than expected.
