    Timea Vitos (Lund University)

    YSF

    The five dominant angular coefficients $A_i$ parametrizing the Drell-Yan process in the Z-boson mass range is examined, differentially in the dilepton transverse momentum $p_T$. The corresponding Lam-Tung relation $A_0-A_2$ was previously found at ATLAS and CMS to deviate from SM higher-order QCD corrections. We investigate if this discrepancy can be due to electroweak effects by calculating...

  29. 28. Measurement of the vector-boson transverse momentum distributions with ATLAS
    Dennis Pudzha (NRC Kurchatov Institute PNPI (RU))
    28/04/2021, 17:10
    YSF

    The transverse momentum distribution of W/Z bosons produced in hadronic collisions is a traditional probe of strong interaction dynamics. The correct modelling of this distribution is important in many physics analyses at the LHC for which the production of W or Z bosons constitutes a significant background. Moreover, it is crucial for a precise measurement of the W boson mass. In this talk...

  30. 13. Probing Higgs self coupling at the future upgraded LHC
    Mr Amit Adhikary (Centre for High Energy Physics, Indian Institute of Science, Bangalore 560012, India)
    28/04/2021, 17:20
    YSF

    A direct measurement of the Higgs self coupling is very crucial to understand the nature of electroweak symmetry breaking. This requires an observation of production of Higgs boson pair, which suffers from very low event rate even at the current LHC run. In our work, we study the prospects of observing the Higgs pair production at the high luminosity run of the 14 TeV LHC (HL-LHC) and also...

  31. 25. Measurement of Higgs to WW in association with a vector boson using the full Run 2 dataset at CMS
    Amandeep Kaur (Panjab University (IN))

    YSF

    In 2012, the observation of the Higgs Boson was announced by the CMS and ATLAS experiments at CERN. Since the discovery, work has continued to measure the Higgs boson couplings and quantum numbers with greater precision. There are several production channels of the Higgs boson and we are searching for the production of the Higgs boson in association with a vector boson in the H→WW decay...

  32. 11. Parton-shower effects in Higgs production via Vector-Boson Fusion
    Johannes Scheller (Eberhard Karls Universität Tübingen)
    28/04/2021, 17:40
    YSF

    We present a systematic investigation of parton-shower and matching uncertainties of perturbative origin for Higgs-boson production via vector-boson fusion. To this end we employ different generators at next-to-leading order QCD accuracy matched with shower Monte Carlo programs, $\texttt{PYTHIA8}$, and $\texttt{HERWIG7}$, and a next-to-next-to-leading order QCD calculation.
    We thoroughly...

  33. 27. Observation of electroweak production of two jets and a Z-boson pair with the ATLAS detector at the LHC
    Shuzhou Zhang (University of Michigan (US))
    28/04/2021, 17:50
    YSF

    The observation of electroweak production of two jets in association with a Z‐ boson pair using 139 fb−1 of pp collision data at √ s = 13 TeV collected by the ATLAS detector at the LHC is reported. Two different final states originating from the decays of the Z boson pair, 4l and 2l2v, are included in the measurements. A significant data excess from the background‐only hypothesis is observed,...

  34. 14. The anomalous Zbb couplings: From LEP to LHC
    Dr Bin Yan (Los Alamos National Laboratory)
    28/04/2021, 18:00
    YSF

    The bottom quark forward-backward asymmetry ($A_{FB}^b$) data at LEP exhibits a long-standing discrepancy with the standard model prediction. We propose a novel method to probe the Zbb interactions through gg → Zh production at the LHC, which is sensitive to the axial-vector component of the Zbb couplings. We demonstrate that the Zh data collected at the 13 TeV LHC can already resolve the...

  35. 35. LHCb: Search for CP violation in D0->KS0KS0 decays
    Giulia Tuci (Universita & INFN Pisa (IT))
    28/04/2021, 18:10
    YSF

    CP violation in the charm system has been observed for the first time by LHCb in 2019. Up to now, the effect has only be seen in a single observable, the Delta-ACP between D0->KK/pipi. Further measurements are therefore important for a better understanding of the physics picture in this novel field, and whether it is purely Standard-Model or not. Among the possible decay channels, the D0→KSKS...

  36. 29. NNLO QCD Predictions for Triphoton Production
    Dr Vasily Sotnikov (Max Planck Institute for Physics)
    28/04/2021, 18:20
    YSF

    In this talk, I am going to present fully-differential NNLO QCD corrections to the hadroproduction of three isolated photons. We employ an implementation of the $q_T$ subtraction formalism within Matrix, and the recent analytic computation of the two-loop amplitudes to achieve a fully-flexible calculation of the triphoton production at NNLO accuracy. This process is on the cutting edge of the...

    Alessandro Da Rold (Universita e INFN Trieste (IT))
    28/04/2021, 18:30
    YSF

    We present recent measurements of triboson processes from the CMS experiment at the LHC. Studies of the rare production of three vector bosons constitute a stringent test of the electroweak sector of the Standard Model, and can be used to probe new physics beyond the energy reach of the LHC. We present the first observation of three massive vector bosons and a search for the production of a W...
