The current neutrino telescopes, ICECUBE and KM3NeT, have ushered in a new era for the fields of particle physics and astrophysics, bringing these two communities closer together and urging further dialogue between these fields. I will start with a short review of the possible sources of extra-terrestrial neutrinos. I will then review the results from these telescopes as well as the prospect of their upgrade and construction of new neutrino telescopes. I will emphasize the serendipity nature of research in this field, with the frenzy of activity following the famous KM3-230213A event as an example. In the end, I will briefly review our paper explaining this unusual and unexpected event which defies a standard model explanation.

Abstract:

With over two decades of active involvement in experimental particle physics, particularly through the CMS experiment at CERN, the School of Particles and Accelerators is pleased to present the 5th IPM Workshop on Experimental Particle Physics. This one-day event will provide an in-depth introduction to the core concepts, methods, and tools used in experimental particle physics.

The workshop is designed to engage graduate students, post-doctoral researchers, and faculty members in exploring the various areas of this dynamic field. Attendees will have the opportunity to gain valuable insights into the latest developments and applications in particle physics research.

This year's workshop will focus on the following topics:
• Introduction to Experimental Particle Physics
• High-Energy Physics Detectors Systems
• Tools for Physics Data Analysis
• Methods of Data Analysis in Particle Physics

Rare flavour-changing processes provide some of the most sensitive probes of physics beyond the Standard Model, often accessing energy scales far above the direct reach of current colliders. Fully exploiting this sensitivity requires precise theoretical control over both short-distance dynamics and long-distance hadronic effects. This talk discusses recent progress in rare B- and K-meson decays aimed at strengthening the theoretical foundations needed to turn precision measurements into robust tests of the Standard Model.
In rare $b\to s\ell\ell$ transitions, persistent tensions with Standard Model predictions motivate model-independent global analyses of current data. These studies systematically assess theoretical uncertainties, with particular emphasis on nonlocal hadronic contributions that can mimic signals of new physics. Data-driven approaches based on analyticity and unitarity, together with first-principles calculations using light-cone sum rules and dispersive methods, provide complementary strategies to disentangle hadronic effects from genuine short-distance contributions, enabling consistent effective-field-theory interpretations and translating precision measurements into quantitative constraints on high-scale new physics.
Rare kaon decays offer an independent and complementary laboratory, where long-distance dynamics play a more prominent role but can be brought under control. New constraints on vector, axial-vector, scalar, and pseudoscalar interactions from charged- and neutral-lepton modes are also highlighted, alongside improved non-perturbative inputs from global analyses of $K \to 3\pi$ data, with implications for ongoing and future high-intensity kaon experiments.

Abstract:

In recent years, exciting connections have emerged between quantum information theory, quantum gravity, and quantum many-body systems, reshaping our understanding of fundamental physics. To explore these developments and foster deeper interdisciplinary links, the School of Particles and Accelerators at IPM has launched an ongoing series of workshops. These events bring together experts and young researchers to review recent progress, exchange ideas, and strengthen collaborations between the quantum information and high-energy physics communities.

Abstract:

I present a quantitative study of how future Electron–Ion Collider (EIC) semi-inclusive DIS (SIDIS) measurements can improve the determination of parton-to-pion fragmentation functions. Using an NLO pQCD framework with a neural-network parametrization and Monte Carlo uncertainty propagation, we perform two global fits: (i) existing SIA and SIDIS data (HERMES and COMPASS), and (ii) the same dataset augmented by EIC SIDIS pseudo-data at. The pseudo-data are generated consistently within the same NLO collinear-factorization framework, with realistic statistical and correlated systematic uncertainties. We find that including EIC pseudo-data leads to a substantial reduction of fragmentation-function uncertainties, most notably at medium-to-large z, with particularly strong gains for selected light-quark channels and a clear improvement for the gluon fragmentation function.

Abstract:

The top quark, as the heaviest known elementary particle, occupies a unique position in the Standard Model and plays a central role in probing fundamental interactions at the electroweak scale. Owing to its extremely short lifetime, the top quark decays before hadronization, allowing its spin information and correlation patterns to be directly transferred to its decay products. This feature makes top-antitop systems an exceptional laboratory for investigating quantum correlations in high-energy processes. In this talk, I explore what quantum correlations can reveal about the underlying physics of top quarks. I discuss how these correlations emerge in top-quark pair production, and how they can be quantified using tools from quantum information theory. I also highlight recent theoretical and experimental advances in accessing quantum correlations at collider experiments, especially at the LHC.

Inflation is the leading paradigm for the dynamics of the early Universe and for the generation of large scale structures in the cosmos. In this talk, we review early universe cosmology and inflationary model buildings and their connections to osmological observations. We also briefly review our recent works on quantum loop corrections in the primordial power spectrum.

Abstract:

Kinetic plasma simulations, such as the Electromagnetic Particle-in-Cell (EMPIC) method, are essential for studying complex phenomena in high-power microwave devices, particle accelerators, and astrophysical plasmas. However, these simulations are computationally expensive due to the large number of particles required for accurate phase-space sampling. In this talk, based on the paper, I will present a novel data-driven reduced-order modeling framework based on Dynamic Mode Decomposition (DMD) to accelerate EMPIC simulations by modeling the space-charge dynamics through the time evolution of plasma current density. The proposed DMD-EMPIC algorithm replaces the computationally intensive particle operations (gather, pusher, scatter) with a low-dimensional DMD model during the post-transient phase, achieving significant speed-ups while maintaining high accuracy. The effectiveness of this approach through several case studies, including oscillating electron beams, virtual cathode oscillations, and backward wave oscillators will be demonstrated.

Abstract:

This conference will cover a broad range of frontier topics in particle physics, including hadron physics, precise Standard Model measurements at the LHC, and global parton distribution function (PDF) analyses. It will also address neutrino physics and theoretical and experimental developments Beyond the Standard Model (BSM).

Looking ahead, the conference will explore the physics potential of future lepton colliders and their role in precision tests of the Standard Model and new physics discovery.
