Search for single production of a vector-like T quark decaying to a top quark and a neutral scalar boson in the lepton+jets final state in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
A search for single production of a vector-like T quark with charge 2$ e$/3, decaying to a top quark and a neutral scalar boson is presented. [...]

Sub-GeV dark matter and multi-decay signatures from dark showers at beam-dump experiments / Bernreuther, Elias (UC, San Diego) ; Hemme, Nicoline (KIT, Karlsruhe, IKP ; KIT, Karlsruhe, TTP) ; Kahlhoefer, Felix (KIT, Karlsruhe) ; Kulkarni, Suchita (Graz U.) ; Ovchynnikov, Maksym (CERN)
In models of strongly-interacting dark sectors, the production of dark quarks at accelerators can give rise to dark showers with multiple dark mesons in the final state. [...]

Exploring the magnetic landscape of easily-exfoliable two-dimensional materials / Haddadi, Fatemeh (Ecole Polytechnique, Lausanne) ; Campi, Davide (Milan Bicocca U.) ; Santos, Flaviano dos (PSI, Villigen ; Ecole Polytechnique, Lausanne) ; Mounet, Nicolas (Ecole Polytechnique, Lausanne ; CERN) ; Ponet, Louis (Ecole Polytechnique, Lausanne) ; Marzari, Nicola (Ecole Polytechnique, Lausanne) ; Gibertini, Marco (U. Modena (main) ; Neuroscience Institute, Italy)
Magnetic materials often exhibit complex energy landscapes with multiple local minima, each corresponding to a self-consistent electronic structure solution. [...]

A Dynamic Energy-Based Hysteresis Model for Pulsed-Operated Fast-Ramping Magnets / Moll, Dominik (Darmstadt, Tech. U.) ; D'Angelo, Laura A.M. (Darmstadt, Tech. U.) ; De Gersem, Herbert (Darmstadt, Tech. U.) ; Boattini, Fulvio (CERN) ; Bottura, Luca (CERN) ; Gast, Marco (KIT, Karlsruhe)
Due to the strongly nonlinear behavior of ferromagnetic yokes, the numerical analysis of fast-ramping magnets is highly cumbersome and, therefore, in practice overly simplified by means of anhysteretic material descriptions and a posteriori loss formulae. [...]

Constrained instantons in scalar field theories / Elder, Benjamin (Imperial Coll., London) ; Gawrych, Kinga (Imperial Coll., London) ; Rajantie, Arttu (CERN ; Imperial Coll., London)
Instantons, localised saddle points of the action, play an important role in describing non-perturbative aspects of quantum field theories, for example vacuum decay or violation of conservation laws associated with anomalous symmetries. [...]

Measurement of the ratio of the B$_\mathrm{c}^+$ $\to$ J/$\psi$ $\tau^+ν_\tau$ and B$_\mathrm{c}^+$ $\to$ J/$\psi$ $\nu^+ν_\nu$ branching fractions using three-prong $\tau$ lepton decays / CMS Collaboration
The ratio between the B$_\mathrm{c}^+$$\to$ J/$ψ$$τ^+ν_τ$ and B$_\mathrm{c}^+$$\to$ J/$ψ$$μ^+ν_μ$ branching fractions is measured using a data sample of proton-proton collisions collected by CMS at a center-of-mass energy of 13 TeV in the years 2016$-$2018 and corresponding to an integrated luminosity of 138 fb$^{-1}$.
