    2. 3. Multi-differential dijet cross sections at the ATLAS experiment
      Ota Zaplatilek
      22/05/2024, 10:00

      Inclusive dijet cross-sections are measured in proton-proton collisions at a center-of-mass energy of 13 TeV. The measurements use a dataset with an integrated luminosity of 139 $fb^{−1}$ recorded in 2015-2018 with the ATLAS detector at the Large Hadron Collider. Jets are identified using the anti-kT algorithm with a radius parameter value of R=0.4. The inclusive dijet cross-sections are...

      22/05/2024, 10:20

      The aim of the work is to obtain energy response and resolution for large-R jets in AtlFast3 (AF3) in R22+.

    6. 8. Bose-Einstein correlations in 3D approach in high energy proton-proton collisions in the ATLAS
      Daniel Suchy (Comenius University (SK))
      22/05/2024, 11:45

      The presentation will focus on investigating Bose-Einstein correlations in a 3D approach within 13 TeV proton-proton collisions. Instead of relying solely on a one-dimensional analysis, we will explore the possibility of characterizing the source radius of particles (R) using two or three components. In this context, we discuss various properties of the source emission probability (especially...

    7. 2. Jet Energy Scale from Hadronic W mass in ttbar
      Adriana Dohnalova (Comenius University (SK))
      22/05/2024, 13:45

      Quarks and gluons emerging from the high energy proton-proton collisions at the Large Hadron Collider are observed as jets. Jet energy scale (JES) calibration is employed to correct the measured energy of the jets to that of the truth jets. A new approach, exploiting $t\bar{t}$ events in single-lepton decay channel is used to calibrate JES. The invariant mass of W boson is reconstructed from...

    8. 4. Observation of top quarks in $p$+Pb collisions at $\sqrt{s_\mathrm{NN}}=8.16\;\mathrm{TeV}$ with the ATLAS detector
      Santu Mondal (Czech Technical University in Prague (CZ))
      22/05/2024, 14:05

      Top quarks, the heaviest elementary particles carrying colour charges, are considered to be attractive candidates for probing the quark-gluon plasma produced in relativistic heavy-ion collisions. In proton-lead collisions, top-quark production is expected to be sensitive to nuclear modifications of parton distribution functions at high Bjoerken-x values, which are difficult to access...

    9. 11. B0 meson lifetime measurement in ATLAS
      Marek Biros (Charles University (CZ))
      22/05/2024, 14:25

      A novel measurement of B0d meson lifetime with ATLAS full Run-2 dataset is presented. Average decay width Γd as well as the Γd/Γs width ratio are also measured. The measurement results are consistent with the Standard Model predictions and with other experiments.

    12. 10. Analysis of AFP/ToF data from early LHC Run-3
      Viktoriia Lysenko (Czech Technical University in Prague (CZ))
      22/05/2024, 15:45

      The analysis of the early LHC Run-3 data was performed. Efficiencies for the ATLAS Forward Proton (AFP) Time-of-Flight (ToF) detector were studied. In addition, these performance studies of the ToF data included the proton-proton vertex reconstruction using matching of ToF and central ATLAS vertex position. After a calibration, a preliminary resolution of the vertex reconstruction was...

      Karel Cerny (Palacky University (CZ))
      22/05/2024, 16:05

      A brief summary will be given accounting on results obtained from a analysis of the very first data recorded by the AFP Time-of-Flight detector in 2017.

      I'll try to describe some concrete studies in areas where further work would be beneficial towards fully understanding the physics potential of an e+e− Higgs / Top / Electroweak factory at the FCC as described in the https://arxiv.org/abs/2401.07564
