Vector boson plus jets measurements at ATLAS / CMS / LHCb / Hugo Alberto Becerril Gonzalez /ATLAS, CMS and LHCB Collaborations
The study of vector boson production in association with jets (V+jets, where V = W, Z, $\gamma$) is a crucial component of the LHC physics program. These processes serve both as stringent tests of perturbative Quantum Chromodynamics (pQCD) and as important backgrounds in searches for new physics and precision measurements, including Higgs boson studies and top quark analyses.

Measurement of the azimuthal anisotropy of charged particles in $\sqrt{s_{\mathrm{NN}}}=5.36$ TeV $^{16}$O$+^{16}$O and $^{20}$Ne$+^{20}$Ne collisions with the ATLAS detector / ATLAS Collaboration
This paper presents the first measurements of the azimuthal anisotropy coefficients $v_{n}$, which quantify the $n^{\mathrm{th}}$-order Fourier modulation of charged-particle azimuthal distributions, for $n=2$-4 in $\sqrt{s_{\mathrm{NN}}}=5.36$ TeV $\mathrm{^{16}O}+\mathrm{^{16}O}$ and $\mathrm{^{20}Ne}+\mathrm{^{20}Ne}$ collisions recorded with the ATLAS detector at the Large Hadron Collider in 2025.

Search for heavy neutral leptons in decays of $W$ bosons produced in 13 TeV $pp$ collisions using prompt signatures in the ATLAS detector / ATLAS Collaboration
The existence of right-handed neutrinos with Majorana masses below the electroweak scale could help address the origins of neutrino masses, the matter-antimatter asymmetry, and dark matter. [...]

Diboson and triboson (except VBS) at ATLAS and CMS / Mecca, Alberto (INFN, Turin ; Turin U.) /ATLAS and CMS Collaborations
Both diboson and triboson production are suited for precision tests of the Standard Model (SM), especially of the Electroweak (EW) sector due to the sensitivity to triple (TGC) and quartic gauge couplings (QGC), making them complementary to the Higgs boson in understanding the Electroweak Symmetry Breaking mechanism. These two classes of processes have cross sections spanning four orders of magnitude. [...]
