Optical Cherenkov Radiation (ChR) is a well-known type of radiation, which is utilized in different fields of physics such as charged particle detection or generation of intense THz radiation. It is also widely used in beam diagnostics, for instance, in beam loss monitors or for bunch length measurements. [...]

A key feature of the, so far only theoretically described, family of sp2 carbon allotropes called schwarzites is the negatively curved topology, which is introduced by the incorporation of heptagonal (or octagonal) rings in a graphene-type lattice. We have constructed a cut-out of this material with a unique pattern of four heptagonal rings arranged in a row by Pd-catalyzed [4 + 3] and [5 + 2] annulation and characterized it thoroughly. [...]

Structural heterogeneity is an inherent feature that occurs practically in all cast materials. In this work, wedemonstrated that the chemical heterogeneity resulting from the SHS reaction of TiC formation in the aluminumAl1000 alloy bath can enhance the strength by refining the matrix grains in in-situ cast TiC/Al1000 composites.Using advanced characterization techniques including X-Ray synchrotron radiation diffraction, (S)TEM-HREMand SEM-EBSD studies, we identified two types of aluminum solid solutions within the dendritic grains of theAl1000 matrix, distinguished by different lattice parameters. [...]

The first observation of single top quark production in association with a W and a Z boson in proton-proton collisions is reported. The analysis uses data at center-of-mass energies of 13 and 13.6 TeV recorded with the CMS detector at the CERN LHC, corresponding to a total integrated luminosity of 200 fb-1. [...]

This paper presents a search for new physics through the process where a massive particle, X, decays into a Higgs boson and a second particle, Y. The Higgs boson subsequently decays into a bottom quark–antiquark pair, which is reconstructed as a single large-radius jet [...]

The first measurement of pseudorapidity and azimuthal angle distributions relative to the momentum vector of a Z boson for low transverse momentum (pT) charged hadrons in lead-lead (PbPb) collisions is presented. By studying the hadrons produced in an event with a high-pT Z boson (40<pT<350GeV), the analysis probes how the quark-gluon plasma (QGP) medium created in these collisions affects the parton recoiling opposite to the Z boson. [...]

A search for nonresonant new physics phenomena in high-mass dilepton events produced in association with b-tagged jets is performed using proton-proton collision data collected in 2016–2018 by the CMS experiment at the CERN LHC, at a center-of-mass energy of 13 TeV corresponding to an integrated luminosity of 138 fb$^{−1}$. The analysis considers two effective field theory models with dimension-six operators; involving four-fermion contact interactions between two leptons (ℓℓ, electrons or muons) and b or s quarks (bbℓℓ and bsℓℓ) [...]
