Analysis of the 4-Cell Problem in the LHCb's Electromagnetic Calorimeter 15m
Jinkyu is an undergraduate physics student at Hanyang University in Seoul, South Korea. He has been working as a research intern with the KCMS Elementary Particle Physics group at his university.
This summer, he has been involved in Data Quality and Monitoring for the LBD group in LHCb, focusing on a project analyzing the 4-Cell Problem in the LHCb electromagnetic calorimeter. This issue, which has been recurring throughout the past year, often goes unnoticed, leaving potentially affected data included in the ntuples used for research. His work has centered on identifying the impact of this problem, understanding its behavior, and assessing whether the data can still be used for specific types of analyses. In this presentation, he will share the details of his investigation, as well as his contributions and insights for future occurrences.

Leonor Guimaraes Goncalves 15m
Understanding neutrino interactions is key to unlocking the full physics potential of DUNE. In this talk, I present a novel data-driven strategy to estimate the $\nu_e/\nu_\mu$ cross-section ratio without relying on interaction models. By exploiting the unique off-axis capabilities of DUNE-PRISM, we construct optimized linear combinations of $\nu_\mu$ fluxes that closely replicate $\nu_e$ fluxes. This allows us to isolate the cross-section effects directly from event rates. The method combines flux matching, regularized minimization, and energy-weighted importance functions—offering a robust and transparent path toward precision neutrino physics.

Developing Neural Networks to Tag Emerging Jets in the ATLAS Experiment 15m
Machine learning algorithms are being developed to search for dark matter in the ATLAS experiment. One class of dark matter models under consideration involves a dark sector containing dark quarks that shower and hadronize into dark mesons. These mesons may travel significant distances before decaying into Standard Model particles, producing topologically distinct emerging jets that can be identified by neural networks. This talk will present improvements to an existing supervised jet tagger, as well as the development of a new unsupervised algorithm aimed at enabling model-independent searches.

Brad Andrew Brown 15m
Hello! My name is Brad Brown and I’m a senior undergraduate physics student at the University of Texas at Arlington. This summer, I worked with the LHCb Simulation team on restoring and modernizing the Machine-Induced Background (MIB) generator — a simulation tool originally developed during Run 1 of the LHC but unused since. MIB arises from beam losses around the accelerator and can impact detector performance. New studies are needed to evaluate MIB conditions for High-Luminosity LHC, Heavy Ion Collisions, and even for future colliders like the FCC. My project involved understanding the relevant accelerator physics, reviving the legacy tool, and porting it into the modern Gauss-on-Gaussino framework. With the generator now operational again, LHCb is equipped to carry out these new studies.

Secondary Vertex Reconstruction with Maskformer
The High-Luminosity Large Hadron Collider will generate data in a challenging high pile-up environment, making the reconstruction of secondary vertices, crucial for identifying heavy-flavor quarks and searching for new physics, extremely difficult. This project addresses this by developing an end-to-end machine learning pipeline using the MaskFormer architecture. The core contribution was creating a highly efficient data conversion module to transform
.rootphysics data into the ML-friendly.h5format. Following this foundational step, the project involves training the model and analyzing its results to ensure physics-accurate predictions. Further enhancements will be explored through advanced techniques such as hyper-parameter tuning, pre-training strategies, and post-training optimizations to maximize the model's performance and scientific potential.Speaker: Sittipon Kumda (CERN)

Ruiyang Xie 15m
In modern high-energy physics experiments like ATLAS, the trigger system plays a crucial role in selecting which events are saved for further analysis. Traditionally, these triggers are designed to capture well-understood Standard Model signatures. However, rare or unexpected signals may evade such targeted selections.
This project focuses on calibrating a novel anomaly detection (AD) trigger—a powerful tool designed to tag unusual events that don't necessarily fit into pre-defined physics categories. I will walk you through how we study its behavior, identify overlaps with standard triggers, and build a calibration framework that will help reduce systematic uncertainties in future BSM searches.

Big Bang Nucleosynthesis: Deuterium Production in the Early Universe 15m
Through the concordance model of cosmology, it is possible to predict the primordial abundances of light elements within the framework of Big Bang Nucleosynthesis (BBN). These predictions agree remarkably well with observations of the primordial abundances of helium-4 and deuterium. Specifically, the deuterium abundance is strongly sensitive to nuclear reaction rates, such as $\text{D}+\text{D}\rightarrow\, ^3\text{He}+n$ or $\text{D}+\text{D}\rightarrow\text{T}+p$. By understanding in what energy ranges more precise measurements of these rates are needed, we hope to improve our knowledge of these rates to allow stronger cosmological inferences to be made from deuterium observations. These in turn allow us to make important improvements in estimating cosmological parameters such as $N_\text{eff}$, the effective number of neutrino species.

Analysis of Central Diffractive Events with the CMS Precision Proton Spectrometer (PPS) 15m
Hello! My name is Ash, I am a physics bachelors student from Canada entering my final year of studies.
In this talk, I present an analysis of central diffractive events in proton–proton collisions using the CMS Precision Proton Spectrometer (PPS). By tagging protons and reconstructing vertex positions via timing detectors, we explore a class of photon-mediated interactions in a non-perturbative QCD regime. We study kinematic distributions in data and simulation, applying event selection, timing correlations, event mixing, and sideband subtraction to estimate and separate background. This is among the first physics analyses using PPS to study central diffraction at LHC energies, providing new insights into a poorly modeled process.

Victor Clarizio Canelon - Characterization of new MPGD Prototypes for Application in Future Hadronic Calorimeters 15m
Hola! My name is Victor Clarizio, 29 years old and currently I'm finishing my Masters Degree in cosmic rays and high energy physics at the Universidad Central de Venezuela in Caracas, Venezuela. Also, I've been a lecturer at the very same university for about one year now. I like to go hiking, love to take pictures and sketch/paint, play football whenever I'm able to, and many other things! I feel honored to be here and to be part of CERN, and I will always treasure this enriching experience.
My project at CERN as Summer Student:
As part of the upcoming gaseous detector technologies, one that stands out from the rest are the Gas Electron Multiplier (GEM) detectors due to its versatility with most of gas fillings (including noble gases), proportional gains above 105, micrometric space resolution, typical energy resolution 18% FWHM at 5.9keV, low cost and robust technology. This presentation contains my work experience regarding the activities as a Non-Member State Summer Student from June, 16th to August, 8th 2025 working in the Gas Detector Development Lab (GDD) at CERN. Over the course of these weeks, I had a hands-on-work experience working on the assembly of MPGD prototypes and set up of a cosmic stand using a triple-GEM detector, alongside my direct supervisor Anna Stamerra and the rest of the team. At the end of the program, I gained invaluable researching experience and skills on experimental physics, instrumentation and data analysis applied to gaseous detectors and MPGD technologies.

Lucia Barreiro Rius - Missing energy signals from b-flavored hadrons at FCCee 15m
b-flavored hadrons decaying into a final state containing missing energy are of key importance to flavor physics, particularly in searches for new physics. In this context, electron-positron colliders running at the Z peak offer key conditions to explore this type of decays due to their clean environment and also because the initial energy is known. Given the high interest on a future TeraZ factory at FCCee, the aim of this project is to explore the type of signals that could be probed with 10^12 Z bosons, specifically very suppressed SM decays and also BSM decays hitting the dark sectors (axion-like particles, dark photons), as well as deeply understand the backgrounds for this measurements.

Hello! I’m Zhoie, a first year master’s student in physics studying at the University of the Philippines Diliman. I joined the High Energy Physics and Phenomenology group at the National Institute of Physics during my third undergraduate year and have been conducting research in particle physics ever since.
Di-Higgs production provides direct sensitivity to the Higgs self coupling parameter. My project focuses on the HH → bbgg channel, which has a relatively high branching ratio but is challenging due to the overwhelming QCD background in the H → gg decay. This analysis uses Monte Carlo simulations to study the separation between H → bb and H → gg jets using jet substructure variables, and to improve their discrimination against the background using track multiplicity cuts and BDT-based tagging.
