$b \to cl\nu$ angular analyses can provide valuable input of understanding New Physics in semileptonic B decays. An angular analysis of the $B^0 \to D^* \mu \nu $ decay is presented utilizing data collected by the LHCb experiment with 3$fb^-1$ integrated luminosity. Measurements of $R(D^*) - R(D)$ show a ~3.2$\sigma$ deviation from Standard Model (SM) predictions, motivating a detailed study...

The search for high-mass Higgs bosons within the Minimal Supersymmetric Standard Model (MSSM) framework represents one of the most compelling flagship analyses of the CMS experiment at the Large Hadron Collider (LHC). The $\tau^+\tau^-$ decay channel provides enhanced sensitivity at high masses due to large branching ratios, but significant challenges arise from Standard Model backgrounds,...

A large part of High Energy Physics is dedicated to correcting wrong distributions due to detector mismodelling, experimental measurement limitations and an insufficient theoretical understanding of non-perturbative processes. This often results in deviations between MC and data distributions, that require a lot of time to correct - especially in very high-dimensional, highly correlated...

The $K^{+}\rightarrow\pi^{+}\nu\bar{\nu}$ decay is a golden mode for flavour physics. Its branching ratio is predicted with high precision by the Standard Model to be less than $10^{-10}$, and this decay mode is highly sensitive to indirect effects of new physics up to the highest mass scales. A new measurement of the $K^{+}\rightarrow\pi^{+}\nu\bar{\nu}$ decay by the NA62 experiment at the...

The High Luminosity LHC (HL-LHC) is set to begin in 2029 and will be Run 4 of the ATLAS detector. As part of the phase 2 upgrade, the ATLAS Inner tracking system will be replaced with an all-silicon Inner Tracker(ITk). The higher luminosity will cause an increase in pileup, the number of interactions per crossing, resulting in more tracks, increasing the computational complexity of track...

Located 1.5 km underground, the LUX-ZEPLIN experiment uses a 7t liquid xenon time projection chamber to search for weakly interacting dark matter (WIMPs) and other beyond-standard-model physics. Interactions between neutrons and xenon are not readily distinguishable from WIMPs. To be able to perform direct detection searches of dark matter, this background must be removed, for which LZ has a...

Particle physics has seen a surge of interest in understanding the impact of quantum computers on the field. From allowing one to more naturally simulate quantum fields to providing aid in the most computationally expensive pieces of analysis, proposals to find useful quantum advantage abound.
While quantum hardware and algorithms are currently still in their early stages, rapid progress...

With the increasing volume and complexity of data, machine learning (ML) models are becoming indispensable tools for identifying patterns within structured datasets. However, as these models grow in complexity, it becomes challenging to determine whether they are truly learning meaningful relationships or capturing unintended artifacts. This lack of interpretability leads to mistrust,...

The High Luminosity upgrade to the LHC (HL-LHC) will increase the rate of proton-proton collisions by a factor of approximately seven, yielding greater statistics for physics analyses but also creating a challenging pileup environment. To exploit the increased luminosity and maintain physics sensitivity, the CMS detector will undergo many significant upgrades, including to its level-1 trigger...

The Mu3e experiment is dedicated to observing charged lepton flavour violation. This is observed through the neutrinoless decay of a muon to two positrons and an electron. The experiment is situated around the Compact Muon Beam Line (CMBL) at the Paul Scherrer Institut, which produces muons at a rate of 10E8 Hz. The experiment aims to observe the decay or exclude a branching ratio greater than...
