35. ALPHA status and resonator development at Stockholm University.

Jacob Lindahl (Stockholm University)

The search for post-inflation axion dark matter has pushed towards axion masses corresponding to frequencies above 10 GHz (40 µeV). As traditional haloscopes are limited by the loss of interaction volume at high frequencies, this has required the development of new techniques. A plasma haloscope employs wire metamaterials where the inter-wire spacing controls the resonant frequency.

36. ALPHA Data analysis and statistical inference

Axions have become increasingly important candidates in searches for dark matter, due to their ability to also resolve the strong CP problem. One of the primary types of axion detectors is the haloscope, using the conversion of axions into photons in a magnetic field. The Axion Longitudinal Plasma Haloscope (ALPHA) experiment aims to search for axions with masses above 40 µeV, a range favored...

34. Particle Reconstruction in a Future Muon Collider

Sarah Douglass (Northeastern University (US))

The Large Hadron Collider (LHC) has driven major discoveries in particle physics, but further exploration of the energy frontier calls for the next generation of machines. A multi-TeV muon collider (MuC) has been proposed as a potential next step, but its implementation hinges on solving major reconstruction concerns. Muon decay produces an overwhelming flux of background noise in the form of...

17. ECal Timing Studies for LHCb's Upgrade II

Andreas Pettersson (Lund University)

17/09/2026, 09:45

The aim of the Upgrade II of the LHCb detector is to operate during Run 5 of the CERN Large Hadron Collider (LHC) at a luminosity of 1·1034 cm−2s−1 to collect a data set of 300 f b−1. The increase in particle densities requires a substantial modification of the present Electromagnetic Calorimeter (ECal). The modules of the new calorimeter, the PicoCal, must feature radiation-hard technologies...

11. Testing for the new Inner Tracker system for ATLAS

Ellen Anna Brandt Sahlberg (Lund University (SE)), Vanshika Anand

17/09/2026, 10:00

The High Luminosity-Large Hadron Collider (HL-LHC) introduces a large increase in luminosity making it necessary to build new detectors that can handle the resulting increase in radiation damage. The most exposed parts will be those closest to the collision point. ATLAS is therefore upgrading their Inner Tracker (ITk) system; the first point of detection. ITk is composed of multiple silicon...

2. The FINESSE beamline at ESS

Linus Persson (Lund University)

17/09/2026, 10:15

The FINESSE beamline is a proposed particle-physics instrument at the European Spallation Source (ESS) in Lund. It is designed to utilise the high cold-neutron brightness, pulsed time structure and long flight path available at ESS to address open questions in particle physics, including baryon number violation, new sources of CP violation and the nature of dark matter.

The primary...
