The paper presents a measurement of the Standard Model Higgs Boson decaying to $b$-quark pairs in the vector boson fusion (VBF) production mode. A sample corresponding to 126 fb$^{-1}$ of $\sqrt{s} =$ 13 TeV proton-proton collision data, collected with the ATLAS experiment at the Large Hadron Collider, is analyzed utilizing an adversarial neural network for event classification. The results are combined with an analysis of Higgs bosons decaying to $b$-quarks, produced via VBF in association...

Exclusive dimuon production in ultraperipheral collisions (UPC), resulting from photon-photon interactions in the strong electromagnetic fields of colliding high-energy lead nuclei, $\mathrm{PbPb}(\gamma\gamma) \rightarrow \mu^+\mu^- (\mathrm{Pb}^{(\star)}\mathrm{Pb}^{(\star)} )$, is studied using $\mathcal{L}_{\mathrm{int}} = 0.48$ nb$^{-1}$ of $\sqrt{s_\mathrm{NN}}=5.02$ TeV lead-lead collision data at the LHC with the ATLAS detector. Dimuon pairs are measured in the fiducial region $p_{\mathrm{T}\mu} > 4$ GeV, $|\eta_{\mu}| < 2.4$, invariant mass $m_{\mu\mu} > 10$ GeV, and $p_{\mathrm{T,\mu\mu}} < 2$ GeV. The primary background...

The H.E.S.S. Gravitational Wave Rapid Follow-up Program

Halim Ashkar, Francois Brun, Matthias Füssling, Clemens Hoischen, Stefan Ohm, Heike Prokoph, Patrick Reichherzer, Fabian Schüssler & Monica Seglar-Arroyo
Gravitational Wave (GW) events are physical processes that significantly perturbate space-time, e.g. compact binary coalescenses, causing the production of GWs. The detection of GWs by a worldwide network of advanced interferometers offer unique opportunities for multi-messenger searches and electromagnetic counterpart associations. While carrying extremely useful information, searches for associated electromagnetic emission are challenging due to large sky localisation uncertainties provided by the current GW observatories LIGO and Virgo. Here we present the methods and procedures...

Integrating Gauge Fields in the $\zeta$-formulation of Feynman's path integral

Tobias Hartung & Karl Jansen
In recent work by the authors, a connection between Feynman's path integral and Fourier integral operator $\zeta$-functions has been established as a means of regularizing the vacuum expectation values in quantum field theories. However, most explicit examples using this regularization technique to date, do not consider gauge fields in detail. Here, we address this gap by looking at some well-known physical examples of quantum fields from the Fourier integral operator $\zeta$-function point of view.

Electroweak pseudo-observables and Z-boson form factors at two-loop accuracy

Ievgen Dubovyk, Ayres Freitas, Janusz Gluza, Tord Riemann & Johann Usovitsch
We present Standard Model predictions for the complete set of phenomenologically relevant electroweak precision pseudo-observables related to the Z-boson: the leptonic and bottom-quark effective weak mixing angles $\sin^2\theta_{\rm eff}^\ell$, $\sin^2\theta_{\rm eff}^b$, the Z-boson partial decay widths $\Gamma_f$, where $f$ indicates any charged lepton, neutrino and quark flavor (except for the top quark), as well as the total Z decay width $\Gamma_Z$, the branching ratios $R_\ell$, $R_c$, $R_b$, and the hadronic cross section $\sigma_{\rm had}^0$. The...

Two-particle azimuthal correlations as a probe of collective behaviour in deep inelastic $\textit{ep}$ scattering at HERA

Two-particle azimuthal correlations have been measured in neutral current deep inelasticep scattering with virtuality Q2 > 5GeV2 at a centre-of-mass energy √s = 318GeVrecorded with the ZEUS detector at HERA. The correlations of charged particles havebeen measured in the range of laboratory pseudorapidity −1.5 < < 2 and transversemomentum 0.1 < pT < 5GeV and event multiplicities Nch up to six times larger thanthe average hNchi ≈ 5. The two-particle correlations have been measured in...

Flavour Violating Axions

Luca Di Luzio
I review the physics case for flavour violating axions. In particular, I argue that relaxing the assumption of the universality of the Peccei-Quinn current opens up new pathways, including: the relaxation of the Supernova bound on the axion mass, a possible connection with the Standard Model flavour puzzle and the experimental opportunity of discovering the axion via flavoured axion searches.

The ILC as a natural SUSY discovery machine and precision microscope: from light higgsinos to tests of unification

Howard Baer, Mikael Berggren, Keisuke Fujii, Jenny List, Suvi-Leena Lehtinen, Tomohiko Tanabe & Jacqueline Yan
The requirement of electroweak naturalness in simple supersymmetric models implies the existence of a cluster of four light higgsinos with mass $\sim 100-300$\,GeV, the lighter the better. While such light compressed spectra may be challenging to observe at LHC, the International Linear $e^+e^-$ Collider (ILC) with $\sqrt{s}>2m_{\rm higgsino}$ would serve as both a SUSY discovery machine and a precision microscope. We study higgsino pair production signatures at the ILC based on full, \texttt{Geant4-}based simulation of...
