24 Novel Neutrino Reconstruction via Acoustic Signals at KM3NeT

Ultra-high-energy neutrinos are a gateway into new physics beyond the Stan-
dard Model, with potentials for unraveling some of the essential mysteries in
cosmology and astrophysics. Given the nature of neutrinos, with electric charge
neutrality and negligible mass, they go through cosmic distances without in-
teracting and will be an excellent candidate for multi-messenger astronomy
in studying celestial objects, especially black holes. It is actually these very
attributes that constitute the difficulties in the attempts at the detection of
neutrinos.
The KM3NeT experiment tackles this challenge by deploying one cubic kilo-
meter of instrumented volume at the bottom of the Mediterranean Sea. This
contribution describes an innovative study related to the detection of ultra-high-
energy neutrinos by means of their acoustic signal; it not only gives additional
information but is also cost-efficient to implement in the frame of the existing
infrastructure called KM3NeT and opens up perspectives for an improvement
of the detection accuracy.
We also recommend advanced computational techniques, namely deep learn-
ing algorithms, for neutrino event reconstruction. These state-of-the-art data
analysis tools will serve to increase the accuracy and reduce the errors associated
with traditional methods, thus helping to advance neutrino astronomy.

Speaker: Amine Meskar (National Centre for Nuclear Research, Warsaw, and experiment KM3NeT.)

25 Prospects for acoustic detection of high-energy astrophysical neutrinos

The KM3NeT (Cubic Kilometer Neutrino Telescope) located in the Mediterranean Sea is the next-generation neutrino Cherenkov observatory. This experiment addresses a few fundamental questions of physics, like neutrino mass hierarchy and the origins of high-energy cosmic rays. KM3NeT consists of two telescopes: ORCA (Oscillation Research with Cosmics in the Abyss) and ARCA (Astroparticle Research with Cosmics in the Abyss). KM3NeT has a state-of-the-art optical module with many sensors including LED beacon, piezo sensors, tilt meter, and hydrophones. This study aims to work on acoustic calibration and acoustic detection of UHE neutrinos. Additionally, the goal is to study these neutrinos with their potential astrophysical counterparts. In the presentation, the strategy of studying the counterparts of the high energy neutrinos will be discussed.

26 Control system for production testing of the ATLAS ITk PP2

The ATLAS (A Toroidal LHC Apparatus) will undergo modernization between 2026 and 2030 to prepare for operations at the high luminosity regime of the HL-LHC (High-Luminosity Large Hadron Collider). To address the challenging radiation levels, higher data rates, and extremely high-occupancy environment, the ATLAS Inner Detector will be upgraded and replaced with a new all-silicon pixel and strip tracker known as the ITk (Inner Tracker). Simultaneously, a detector control system (DCS) is being developed for the ITk to ensure the proper functioning of each part of the new detector. Patch Panel 2 (PP2) is an active component of the strip tracker's power supply (PS) chain, which will be located inside the ATLAS detector. It will connect two different types of cables within the PS system and convert the 48V voltage delivered from service caverns to the 12V required for the ITk Strip detector structures. An independent readout system is needed to connect to PP2 for safety and control reasons. Currently, the PP2 system is in the pre-production phase. The equipment must undergo detailed Quality Control (QC) checks before being installed in the ITk detector. A dedicated DCS system is being developed to facilitate the automated QC procedure. I will present the PP2 design during its prototype phase, along with its readout system and the plans for the QC of the pre-production PP2 series, which are being developed in Cracow.

Speaker: Maria Malgorzata Dudek (Polish Academy of Sciences (PL))

27 Towards automatizing Higgs decays in BSM models at one-loop in the decoupling renormalization scheme

High-precision calculations of Higgs boson observables can be used to constrain models of the Beyond the Standard Model (BSM) physics. Motivated by the non-observation of light BSM particles at the LHC, in this talk I will discuss a renormalization scheme for precise predictions of Higgs boson decays in the presence of a moderatelly heavy BSM physics at the 1-loop level. I will cover the basics of the decoupling renormalization scheme and present the renormalization conditions for a generic model. I will also show application of the decoupling scheme in a concrete model to explore its effects. This calculation is a part of FlexibleSUSY spectrum-generator generator and will be automatically applied to any user defined BSM model in the future.

40 All non-local states of identical particles, or when indistinguishability is a resource

Entanglement due to symmetrisation of the wave function in the second-quantised theory is ubiquitous, but at the same time it is severely constrained by the inability to address individual particles. So, can it actually be turned into a useful resource of non-local correlations observed in a laboratory? I will show that this is possible with very modest passive linear optical means for almost every state of identical particles.

Speaker: Paweł Błasiak (IFJ PAN)

prof. Zalewski's session

41 Lecturer, Teacher and Mentor: What I have learned from Professor Zalewski?

Among Krakow physicists, Professor Zalewski is an iconic figure. Many of us attended his lectures, discussed solutions to problems assigned "for home" while standing at the blackboard, and trembled in front of the Professor's office door waiting to enter the exam. It was hard at times, but it was worth it. Not only for a better understanding of physics, not only for the ability to patiently convey it, but, perhaps above all, for the "life wisdom" that Professor Zalewski always emanated.

Speaker: Andrzej Horzela (IFJ PAN)
