In LHC Run 3, the upgraded ALICE detector will record Pb-Pb collisions at a rate of 50 kHz using continuous readout. The resulting stream of raw data at 3.5 TB/s has to be processed with a set of lossy and lossless compression and data reduction techniques to a storage data rate of 90 GB/s while preserving relevant data for physics analysis. This contribution presents a custom lossless data compression scheme based on entropy coding as the final component in the data reduction chain which has to compress the data rate from 300 GB/s to 90 GB/s. A flexible, multi-process architecture for the data compression scheme is proposed that seamlessly interfaces with the data reduction algorithms of earlier stages and allows to use parallel processing in order to keep the required firm real-time guarantees of the system. The data processed inside the compression process have a structure that allows the use of an rANS entropy coder with more resource efficient static distribution tables. Extensions to the rANS entropy coder are introduced to efficiently work with these static distribution tables and large but sparse source alphabets consisting of up to 25 Bit per symbol. Preliminary performance results show compliance with the firm real-time requirements while offering close-to-optimal data compression.
在LHC Run 3中，升级后的ALICE探测器将以50 kHz的速率连续读出记录Pb-Pb碰撞。由此产生的3.5 TB/s的原始数据流必须通过一组有损和无损压缩和数据缩减技术进行处理，使存储数据速率达到90 GB/s，同时保留相关数据用于物理分析。本文提出了一种基于熵编码的自定义无损数据压缩方案，该方案作为数据缩减链的最后组成部分，必须将数据速率从300 GB/s压缩到90 GB/s。提出了一种灵活的多进程数据压缩方案架构，该架构与早期阶段的数据缩减算法无缝接口，并允许使用并行处理，以保持系统所需的坚固实时性保证。在压缩过程中处理的数据具有一种结构，该结构允许使用具有更高效资源的静态分布表的rANS熵编码器。引入了对rANS熵编码器的扩展，以有效地处理这些静态分布表和由每个符号最多25位组成的大型但稀疏的源字母表。初步的性能结果表明，在提供接近最佳的数据压缩的同时，符合公司的实时要求。

High-brightness muon beams of energy comparable to those produced by state-of-the-art electron, proton and ion accelerators have yet to be realised. Such beams have the potential to carry the search for new phenomena in lepton-antilepton collisions to extremely high energy and also to provide uniquely well-characterised neutrino beams. A muon beam may be created through the decay of pions produced in the interaction of a proton beam with a target. To produce a high-brightness beam from such a source requires that the phase space volume occupied by the muons be reduced (cooled). Ionization cooling is the novel technique by which it is proposed to cool the beam. The Muon Ionization Cooling Experiment collaboration has constructed a section of an ionization cooling cell and used it to provide the first demonstration of ionization cooling. We present these ground-breaking measurements.

The next generation of neutrino experiments will require improvements to detector simulation and event reconstruction software matching the reduced statistical errors and increased and precision of new detectors. Here we present progress for the software of the Hyper-Kamiokande experiment being developed to enable reduction of systematic errors to below the 1% level. The current status and future prospects of this software is be presented, including advances in detector simulation and reconstruction using traditional techniques as well as new developments using modern machinelearning based approaches.

The former result is based on a data sample of $121.4~textrm{fb}^{-1}$ recorded at the $Upsilon(5S)$ resonance while the later results are obtained from a $711~textrm{fb}^{-1}$ of data sample collected at $Upsilon(4S)$ resonance with the Belle detector at the KEKB $e^+e^-$ collider. We observe no significant signal for the decays and set upper limit on their branching fractions at 90% confidence level of $mathcal{B}(B_stoeta^{prime}eta)<7.1times 10^{-5}$, $mathcal{B}(B^0totextrm{invisible})<7.8times 10^{-5}$ and $mathcal{B}(B^0totextrm{invisible}+gamma)<1.6times 10^{-5}$.

The upgrade of the Large Hadron Collider to the High Luminosity LHC is required to probe the physics beyond Standard Model. After the ongoing long shutdown and eventually after LS3 in 2026, the accelerator luminosity will be increased up to 7 times as compared to design luminosity (1034 cm−2s−1). To meet the requirements of higher rates environment of HL-LHC era, the muon system of ATLAS detector needs to be upgraded. Therefore, the present small wheel will be replaced by the New Small Wheel, which will be constituted by MicroMegas micro-pattern gaseous detectors and small-strip Thin Gap Chambers. The methods adopted to achieve the challenging required geometrical precision of Micromegas chambers are presented. Specific measurement devices have been developed in the last few years to determine the mechanical metrology quality of Micromegas chambers, required for NSW. Planarity measurements of panels as well as modules after assembly are done with a specifically developed co-ordinate measuring machine. The methodology and the results will be presented. Results of in-plane measurements performed using Rasnik masks etched on the PCBs are also reported.

After operating for 10 years, the LHCb detector at the LHC is currently undergoing a major upgrade. New tracking detectors will be installed to improve tracking performance and to allow taking data at higher instantaneous luminosity than in previous runs. Front-end readout electronics of all subsystems is being replaced by boards with readout at collision frequency of 40 MHz. That will allow application of software-only trigger and prompt data analysis techniques. The Upstream Tracker (UT) will be located in the fringe field in front of the LHCb spectrometer magnet and will be composed of four layers of silicon strip sensors. Custom hybrid flexible circuits and front-end readout chip, SALT, were developed for powering and processing measured signals and to transfer them to the near-detector electronics. This contribution describes the design of UT components, their novel features and detector performance measured during system tests. The current status of installation and commissioning plans are also given.

We present new results on contributions of the QCD condensates to the two-point and the threepoint Green functions of chiral currents, calculated within the means of the operator product expansion (OPE). Further, for the Green functions of the odd-intrinsic parity sector of QCD, we show up-to-date knowledge of behavior of the matching between the calculations performed in the resonance chiral theory and OPE. This matching, however, as complicated as it is, can lead to important constraints on the coupling constants of the resonance Lagrangian, relevant in the odd-sector of QCD.
