Since the discovery of a Higgs boson by the ATLAS and CMS experiments at the LHC, the emphasis has shifted towards measurements of its properties and the search for less sensitive channels in order ...to determine whether the new particle is the Standard Model (SM) Higgs boson. Of particular importance is the direct observation of the coupling of the Higgs boson to b-quarks. In this talk a review of ATLAS results in the search for the Higgs boson in the VH production mode with the Higgs decaying to a b-quark pair will be given.
The fast reconstruction of charged particle tracks with high efficiency and track quality is an essential part of the online data selection for the ATLAS experiment at the High-Luminosity LHC. ...Dedicated custom designed hardware boards and software simulations have been developed to assess the feasibility of a Hardware Tracking Trigger (HTT) system. The Pattern Recognition Mezzanine (PRM), as part of the HTT system, has been designed to recognize track candidates in silicon detectors with Associative Memory ASICs and to select and reconstruct tracks using linearized algorithms implemented in an Intel Stratix 10 MX FPGA. The highly parallelized FPGA design makes extensive use of the integrated High-Bandwidth-Memory. In this paper, the FPGA design for the PRM board is presented. Its functionalities have been verified in both simulations and hardware tests on an Intel Stratix 10 MX development kit.
This report presents a short summary of the activities of the "Standard Model" working group for the "Physics at TeV Colliders" workshop (Les Houches, France, 12-30 June, 2023).

•Cascade biorefinery of Gracilaria g., seaweed harvested in Lesina Lagoon performed.•R-phycoerythrin, allophycocyanin, and phycocyanin were primary extracted.•Extraction’s residue ...pyrolyzed for bio-oil and biochar production, at 400–600°C.•High bio-oil yielded (∼65wt%) but not suitable for fuel without de-nitrogenation.•Pyrolytic char (26.5–33wt%) including P, K, Ca, Fe and Mg, suggested as biochar.
Phycobiliproteins extraction (primary refining) from Gracilaria gracilis seaweed, harvested in Lesina Lagoon (Italy) and further valorization of the residual algal via pyrolysis (secondary refining), were investigated with a cascade biorefinery approach. R-phycoerythrin (7mg/g d.w.), allophycocyanin (3.5mg/g d.w.) and phycocyanin (2mg/g d.w.) were the main phycobiliproteins extracted. Pyrolysis of G.gracilis residue followed, aiming to investigate the production of bio-oil and biochar within a pyrolysis temperature range of 400–600°C. Results showed that the bio-oil yield is high (∼65wt%) at pyrolysis temperature ∼500°C, but its high content in nitrogenous compounds prevents its use as a biofuel, unless some further de-nitrogenation takes place. Biochar yield ranged between 33wt% (400°C) and 26.5wt% (600°C). Interestingly, inorganic nutrients including P, K, Ca, Fe and Mg were detected in biochar, suggesting its potential use as recovering system of natural mineral resources from the oceanic reservoir.
