Abstract Jet flavour tagging is crucial in experimental high-energy physics. A algorithm, - , presented, which exploits a transformer-based neural network that substantially faster to train than state-of-the-art graph networks. The algorithm uses information from particle flow-style objects and secondary vertex reconstruction for b c -jet identification, supplemented by additional not always included algorithms at the LHC, such as reconstructed $$K_{S}^{0}$$ <mml:math...

Abstract The development of instrumentation for operation in high-radiation environments represents a challenge various research fields, particularly particle physics experiments and space missions, drives an ever-increasing demand irradiation facilities dedicated to radiation hardness studies. Depending on the application, different needs arise terms type, energy dose rate. In this article, we present versatile installation based medical cyclotron located at Bern University Hospital...
Long-lived particles (LLPs) are highly motivated signals of physics Beyond the Standard Model (BSM) with great discovery potential and unique experimental challenges. The LLP search programme made advances during Run 2 Large Hadron Collider (LHC), but many important regions signal space remain unexplored. Dedicated triggers crucial to improve searches, their development expansion is necessary for full exploitation new data. public discussion has therefore been a relevant theme in recent...
The FCC-ee is a proposed future $e^+e^-$ collider aimed at producing an unparalleled number of Higgs, $Z$, and $W$ bosons, as well top quarks, in very clean experimental conditions. Numerous measurements the rely on precise accurate measurement location primary secondary vertices. This work presents implementation IDEA vertex detector full simulation using Key4hep DD4hep frameworks widely used by communities. represented great detail, correct stack materials for support, cooling readout...
Analogue test structures were fabricated using the Tower Partners Semiconductor Co. CMOS 65 nm ISC process. The purpose was to characterise and qualify this process optimise sensor for next generation of Monolithic Active Pixels Sensors high-energy physics. technology explored in several variants which differed by: doping levels, pixel geometries pitches (10-25 $\mu$m). These have been tested following exposure varying levels irradiation up 3 MGy $10^{16}$ 1 MeV n$_\text{eq}$ cm$^{-2}$. Here...
This document presents the outcomes of a comprehensive survey conducted among early career researchers (ECRs) in academic particle physics. Running from September 24, 2022, to March 3, 2023, gathered responses 759 ECRs employed 39 countries.

Jet flavour tagging is crucial in experimental high-energy physics. A algorithm, \texttt{DeepJetTransformer}, presented, which exploits a transformer-based neural network that substantially faster to train. The \texttt{DeepJetTransformer} uses information from particle flow-style objects and secondary vertex reconstruction as standard for $b$- $c$-jet identification supplemented by additional information, such reconstructed V$^0$s $K^{\pm}/\pi^{\pm}$ discrimination, typically not included...
Since its inception, the Large Hadron Collider (LHC) has significantly advanced particle physics and will continue to do so in context of High Luminosity LHC (HL-LHC) program collect $3000$ fb$^{-1}$ by end 2041. The community worldwide is discussing which future collider could follow footsteps uncover yet inaccessible phenomena. To foster discussion on this important topic among young physicist community, Early-Career Researchers (ECR) panel European Committee for Future Colliders (ECFA)...

Early-career researchers (ECRs) play a crucial role in current particle physics experiments such as at the Large Hadron Collider. Because future can take decades to be conceptualised, designed and built, today's ECRs are leaders of tomorrow. In 2021, ECFA ECR Panel conducted survey collect community input on training instrumentation for Detector R&D Roadmap Symposium Training. Additionally, this poll also pointed issues that facing lack networking opportunities, missing recognition...
