SUMMARY:Santiago Tanco: Bayesian tools for the LHC: a proof of concept in di-Higgs searches
DESCRIPTION:Extracting reliable physical information from collider data requires a combination of mathematical\, computational and statistical tools to model observed distributions\, often with the help of powerful simulations. But when simulations cannot be fully trusted\, data-driven approaches become indispensable. In this talk\, I will present Bayesian tools that provide a flexible\, data-driven method for unsupervised training on probabilistic models of collider observables\, highlighting their advantages for parameter inference and uncertainty estimation. I will illustrate these points in the context of pp > hh > bbbb searches\, where recent analyses use a variation of the widely used data-driven “ABCD method”. Within our framework\, the ABCD method can be generalized and improved\, especially when its assumptions are not exactly satisfied\, leading to more robust background subtraction. Our approach is able to exploit correlations in multi-dimensional data by modelling kinematic variables and b-tagging scores at the event level. These results also show a way in which simulations can be used as guides for unsupervised estimation of the true data distributions. Based on 2402.08001 and ongoing research.\nhttps://indico.ijs.si/event/3054/

SUMMARY:Franci Merzel\, "Why are atomistic simulations (still) fascinating?"
DESCRIPTION:In this lecture\, I will touch upon the development of methods and examples of the use of simulations in studying basic phenomena such as hydration of biomolecules\, ligand binding\, mechanisms related to biological function. We will also focus on the role of simulations in the interpretation of experimental data\, especially in connection with neutron scattering\, vibrational and NMR spectroscopy and cryo-electron microscopy. We will also talk about methodological solutions for overcoming size and time scales in MD simulations and about the importance of atomistic simulations in the age of AI.\nhttps://indico.ijs.si/event/3052/

SUMMARY:Manuel Morales: Parton distribution perspectives: future facilities and interplay with new physics
DESCRIPTION:The precise determination of parton distribution functions (PDFs) is essential for accurate predictions of observables at hadron colliders. In this seminar\, we will explore two complementary aspects of the future of PDF studies. The first concerns the potential of upcoming experimental facilities (e.g. a muon collider) to provide new constraints on PDFs and other parameters of interest. The second focuses on their interplay with signals of new physics: since PDFs are generally extracted under Standard Model (SM) assumptions\, inconsistencies may arise when they are used to interpret or predict beyond the SM (BSM) phenomena. In this seminar\, we will introduce and discuss key aspects of this PDF–BSM interplay and its broader implications for collider phenomenology.\nhttps://indico.ijs.si/event/3076/

SUMMARY:Benjamin Fuks: Seeking a coherent explanation of LHC excesses for compressed spectra
DESCRIPTION:The most recent searches by the LHC collaborations in final states with soft leptons and missing transverse energy show mild excesses which can result from decays of electroweakinos featuring a compressed spectrum. We demonstrate that while recent searches in the monojet channel can exclude some of the associated parameter space regions\, they exhibit overlapping excesses in certain models\, including a simplified scenario with pure higgsinos. We further explore an array of models that go beyond the simplified scenarios considered by the experimental collaborations\, and show that the excesses persist in realistic supersymmetric models featuring a bino-like lightest supersymmetric particle with some wino admixture. On the other hand\, for the Next-to-Minimal Supersymmetric Standard Model with a singlino-like lightest supersymmetric particle and higgsino-like next-to-lightest supersymmetric particles\, the excess in the two-lepton channel fits rather well with the parameter space predicting the correct relic abundance through freeze out\, but the monojet fit is much poorer. Interestingly\, the excesses either do not overlap or do not exist at all for two non-supersymmetric models seemingly capable of producing the correct final states.\nhttps://indico.ijs.si/event/3029/
