(DNP) M3-4 Testing the Standard Model at low and intermediate energies | Tester le modèle standard à des énergies faibles et intermédiaires (DPN)

The weak mixing angle can be measured in parity-violating elastic electron-proton scattering. The aim of the P2 experiment is a very precise measurement of the weak mixing angle with an accuracy of 0.15% at a low four-momentum transfer of Q2 = 4.5x10^{-3} GeV^2. In combination with existing measurements at the Z pole with comparable accuracy, this comprises a test of the standard model with a...
High Voltage Monolithic Active Pixel Sensors (HVMAPS) are a new type of electron detector. This hybrid pixel detector combines the semiconductor sensor elements that detect high energy particles with the readout electronics in one element. The demand for fast, high resolution and low noise detectors by experiments conducted at the LHC initiated the development of hybrid pixel detectors, first...
The TRIUMF Ultracold Advanced Neutron (TUCAN) source, when completed, will be a world-leading source of ultracold neutrons. The source is a unique combination of a spallation target coupled to a superfluid helium converter. A key component of the source is the liquid deuterium moderator, which surrounds the superfluid helium converter. The goal of the LD$_2$ moderator is to provide a high...
In order to search for the physics beyond the Standard Model at the precision frontier, it is sometimes essential to account for Next-to-Next-Leading Order (NNLO) corrections theoretical calculations. Using the covariant approach, we calculated the QED type leptonic tensor up to quadratic (one loop squared) NNLO (alpha cube) order, which can be used for the processes like (electron-proton) and...
Performing measurements on anti-matter atoms is an alluring proposition for studying the symmetries between matter and anti-matter; however, it presents a number of technical challenges. The ALPHA group has met these challenges and successfully trapped large numbers of anti-hydrogen atoms, opening the door for many such measurements. The new ALPHA-g experiment has the ability to measure the...
The ALPHA-g experiment at CERN aims to test the fundamental symmetry between matter and antimatter by precisely measuring the effect of Earth's gravity on antihydrogen atoms. To achieve this goal, the experiment uses a radial Time Projection Chamber (rTPC) as the primary detector for particle tracking. The rTPC provides a high spatial resolution of the antihydrogen annihilation vertices, which...
