A new look at the estimation of the PDF uncertainties in the determination of electroweak parameters at hadron colliders / Bagnaschi, E. ; Vicini, A.
We discuss the determination of electroweak parameters from hadron collider observables, focusing on the $W$ boson mass measurement. [...]

The EFT and FCNC interpretations in the processes with top quarks at CMS / Skovpen, Kirill
In absence of any distinct evidence of new physics phenomena at the LHC, an increasing number of experimental studies aim at probing anomalous effects with an effective field theory (EFT) that represents a comprehensive approach for interpretation of various experimental results. [...]

A fresh look at the gravitational-wave signal from cosmological phase transitions / Alanne, Tommi (Heidelberg, Max Planck Inst.) ; Hugle, Thomas (Heidelberg, Max Planck Inst.) ; Platscher, Moritz (Heidelberg, Max Planck Inst.) ; Schmitz, Kai (CERN)
Many models of physics beyond the Standard Model predict a strong first-order phase transition (SFOPT) in the early Universe that leads to observable gravitational waves (GWs). [...]

CLICTD: A monolithic HR-CMOS sensor chip for the CLIC silicon tracker / Kremastiotis, Iraklis (KIT - Karlsruhe Institute of Technology (DE)) ; Ballabriga Sune, Rafael (CERN) ; Dort, Katharina (Justus-Liebig-Universitaet Giessen (DE)) ; Egidos Plaja, Nuria (University of Barcelona (ES)) ; Munker, Magdalena (CERN)
The CLIC Tracker Detector (CLICTD) is a monolithic pixelated sensor chip produced in a 180 nm imaging CMOS process with a high-resistivity epitaxial layer. The chip, designed in the context of the CLIC tracking detector study, comprises a matrix of 16 × 128 detector channels, each measuring 300 × 30 μm$^2$ . [...]

Spontaneously Breaking Non-Abelian Gauge Symmetry in Non-Hermitian Field Theories / Alexandre, Jean ; Ellis, John ; Millington, Peter ; Seynaeve, Dries
We generalise our previous formulation of gauge-invariant PT-symmetric field theories to include models with non-Abelian symmetries and discuss the extension to such models of the Englert-Brout-Higgs-Kibble mechanism for generating masses for vector bosons. [...]
