    Poster Session (I)

    We study new physics contributions to Wtb anomalous couplings in top-quark decay process t-> Wb at the partonic level. In particular, we compute the limits on anomalous couplings to Wtb vertex. Limits were obtained at 13 TeV LHC energy with an integrated luminosity of 36.1 fb^-1 and predictions for future circular colliders, namely, HL-LHC, HE-LHC and FCC-hh were given. For future colliders,...

    For the High-Luminosity LHC, planned to start in 2027, the ATLAS experiment will be equipped with the Hardware Tracking for the Trigger (HTT) system, a dedicated hardware system able to reconstruct tracks in the silicon detectors with short latency. The evolved TDAQ system design consists of a two-level hardware trigger in which the HTT is used in a low-latency mode (L1Track), providing tracks...

    The Inner Detector (ID) trigger plays an essential role in the ATLAS trigger system, enabling the high purity reconstruction of physics objects - electron, tau, muon, bjet candidates, providing access to regions of the phase space populated by these objects which span a wide range of kinematic regimes. These are essential for the core physics programme at ATLAS: Standard Model measurements;...

    Muon triggers are essential for studying a variety of physics processes in the ATLAS experiment, including both standard model measurements and searches for new physics. The ATLAS muon trigger consists of a hardware-based system (Level-1), as well as a software-based reconstruction (High-Level Trigger). The muon triggers have been optimised during Run 2 to provide a high efficiency while...

    The ATLAS experiment aims to record about 1 kHz of physics collisions. This is achieved by using a two-level trigger system to select interesting physics events while reducing the data rate from the 40 MHz LHC crossing frequency. Events are selected based on physics signatures such as the presence of energetic leptons, photons, jets or large missing energy. The wide physics programme carried...

    Experimental poster
    Poster Session (I)

    In preparation for LHC Run 3 ALICE will upgrade its subsystems to cope with the increased interaction rate of 50 kHz in Pb-Pb and up to 1 MHz in other collision systems, resulting in the data throughput from the detector up to 3 TB/s. Storing and analyzing such amount of data is a significant challenge and therefore, the online event selection will be required.

    Although the Standard Model successfully explains most phenomena at the LHC, there are several outstanding questions, including the nature of dark matter, the origin of neutrino masses, and the asymmetry in matter and anti-matter abundances in the Universe. Located in the side tunnel TI12, FASER (Forward Search Experiment) will search for highly displaced signals from light and extremely...

    The ATLAS level-1 calorimeter trigger (L1Calo) is a hardware-based system that identifies events containing calorimeter-based physics objects, including electrons, photons, taus, jets, and missing transverse energy. In preparation for Run 3, when the LHC is expected to run at higher energy and instantaneous luminosity, L1Calo is currently implementing a significant programme of planned...

    Poster Session (I)

    A new method for identifying hints of possible beyond the standard model (BSM) signals with energetic high jet multiplicity final states is proposed. In particular, the QCD background is estimated in a data driven way. Based on the simplified picture where QCD multijet events are created from a 2$\to$2 process followed by cascade branching of the outcoming partons, the proposed “Two...

    Heavy Ions
    Experimental poster
    Poster Session (I)

    Ultraperipheral Collisions (UPC) occur when the interacting nuclei or protons have an impact parameter larger than the sum of their radii. They are mediated by virtual photon exchange. The photoproduction of heavy vector mesons is especially interesting because they couple to the photon.

    The ALICE Collaboration has analysed both p-Pb and Pb--Pb UPC at the centre-of-mass energy of...

    Experimental poster
    Poster Session (I)

    To compute cross sections in proton-proton collisions, parton distribution functions (PDFs) are used which describe the density of partons within the proton. In nuclear environments, such as heavy ions, these densities change and therefore PDFs must be modified to nuclear PDFs (nPDFs). Measurements of electroweak bosons help to constrain the nPDFs. This in turn allows to compute cross sections...
