In multiple beyond the standard model (SM) scenarios, the 125 GeV Higgs boson (H) can decay to light pseudoscalars (a), each of which decay into two photons, resulting in a four photon final state. We present a search for exotic decays of the SM Higgs boson in the four photon final state using 132 fb − 1 of proton-proton collision data collected by the CMS experiment at a center-of-mass energy of 13 TeV. This analysis probes pseudoscalars that range in mass from 15 GeV to 60 GeV and decay into photons that are reconstructed as resolved objects in the CMS electromagnetic calorimeter. Although the branching fraction for a → 𝛾𝛾 is subdominant, the low backgrounds in the four photon final state make it important to study. These new results, the first in the four photon final state from CMS, set limits on the product of the production cross-section of the SM Higgs boson times the branching ratio of H → 𝑎𝑎 → 𝛾𝛾𝛾𝛾 , as a function of pseudoscalar mass.

The outstanding performance of the LHC during Run 2 data taking let the ATLAS Experiment to collect a massive dataset of ?? collision at √ B = 13 TeV. This impressive availability of data to analyse paves the way to the research of rare events, as test of the Standard Model validity. One of the most interesting process is the production of CC̄CC̄, an ultra rare process predicted by the Standard Model and very sensitive to new physics contribution. The ATLAS experiment has targeted the measurement of this process in two separate analyses, focused in two different detection channels. These analyses led to the first evidence of CC̄CC̄ production with an observed (expected) significance of 4.7 (2.6) standard deviations in their combination.
大型强子对撞机在Run 2数据采集过程中的出色表现，使ATLAS实验能够收集到海量的??以√B = 13 TeV的速度碰撞。这种令人印象深刻的可用数据分析为罕见事件的研究铺平了道路，作为标准模型有效性的检验。最有趣的过程之一是CC * CC *的产生，这是一个由标准模型预测的极其罕见的过程，对新的物理贡献非常敏感。ATLAS实验针对这一过程进行了两个独立的分析，集中在两个不同的检测通道上。这些分析得出了CC / CC /产生的第一个证据，在它们的组合中观察到(预期)显著性为4.7(2.6)个标准差。

The High-Luminosity phase of LHC, delivering five times the LHC nominal instantaneous luminosity, is scheduled to begin in late 2027. The ATLAS Tile Hadronic Calorimeter (TileCal) will need new electronics to meet the requirements of a 1 MHz trigger, higher radiation dose, and to ensure sound performance under high pile-up conditions. Both the onand off-detector TileCal electronics will be replaced during the shutdown of 2025-2027. PMT signals from every TileCal cell will be digitized and sent directly to the back-end electronics, where the signals are reconstructed, stored, and sent to the first level of trigger at a rate of 40 MHz. This will provide better precision of the calorimeter signals used by the trigger system and will allow the development of more complex trigger algorithms. The TileCal upgrade program has undergone extensive R&D and beam tests. A "demonstrator" module has been tested in actual detector conditions. We present the results of these studies.
