The Einstein Telescope (ET), the European project for a third-generation gravitational-wave detector, has a reference configuration based on a triangular shape consisting of three nested detectors with 10 km arms, where in each arm there is a `xylophone' configuration made of an interferometer tuned toward high frequencies, and an interferometer tuned toward low frequencies and working at cryogenic temperature. Here, we examine the scientific perspectives under possible variations of this reference design. [...]

Tests of General Relativity with GWTC-3 / LIGO Scientific Collaboration
The ever-increasing number of detections of gravitational waves (GWs) from compact binaries by the Advanced LIGO and Advanced Virgo detectors allows us to perform ever-more sensitive tests of general relativity (GR) in the dynamical and strong-field regime of gravity. [...]

Search for Subsolar-Mass Binaries in the First Half of Advanced LIGO’s and Advanced Virgo’s Third Observing Run / LIGO Scientific Collaboration
We report on a search for compact binary coalescences where at least one binary component has a mass between 0.2 $M_\odot$ and 1.0 $M_\odot$ in Advanced LIGO and Advanced Virgo data collected between 1 April 2019 1500 UTC and 1 October 2019 1500 UTC. We extend previous analyses in two main ways: we include data from the Virgo detector and we allow for more unequal mass systems, with mass ratio $q \geq 0.1$. [...]

First joint observation by the underground gravitational-wave detector KAGRA with GEO 600 / KAGRA Collaboration
We report the results of the first joint observation of the KAGRA detector with GEO600. KAGRA is a cryogenic and underground gravitational-wave detector consisting of a laser interferometer with three-kilometer arms, and located in Kamioka, Gifu, Japan. [...]

A New Boson with a Mass of 125 GeV Observed with the CMS Experiment at the Large Hadron Collider / CMS Collaboration
The Higgs boson was postulated nearly five decades ago within the framework of the standard model of particle physics and has been the subject of numerous searches at accelerators around the world. Its discovery would verify the existence of a complex scalar field thought to give mass to three of the carriers of the electroweak force—the W+, W–, and Z0 bosons—as well as to the fundamental quarks and leptons. [...]

Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC / CMS Collaboration
Results are presented from searches for the standard model Higgs boson in proton-proton collisions at $\sqrt{s}$=7 and 8 TeV in the CMS experiment at the LHC, using data samples corresponding to integrated luminosities of up to 5.1 inverse femtobarns at 7 TeV and 5.3 inverse femtobarns at 8 TeV. The search is performed in five decay modes: $\gamma\gamma$, ZZ, WW, $\tau^+ \tau^-$, and $b\bar{b}$. [...]

Exclusive $\gamma\gamma \to \mu^{+}\mu^{-}$ production in proton-proton collisions at $\sqrt{s}$ = 7 TeV / CMS Collaboration
A measurement of the exclusive two-photon production of muon pairs in proton-proton collisions at $\sqrt{s}$=7 TeV, pp → pμ + μ −p, is reported using data corresponding to an integrated luminosity of 40 pb−1. For muon pairs with invariant mass greater than 11.5 GeV, transverse momentum p T (μ) > 4 GeV and pseudorapidity |η(μ)| < 2.1, a fit to the dimuon p T (μ + μ −) distribution results in a measured cross section of σ(p → pμ + μ −p) = 338+058−055 (stat.) ± 0.16 (syst.) ± 0.14 (lumi.) pb, consistent with the theoretical prediction evaluated with the event generator Lpair.

Measurement of the Rapidity and Transverse Momentum Distributions of Z Bosons in pp Collisions at $\sqrt{s}$=7 TeV / CMS Collaboration
Measurements of the normalized rapidity (y) and transverse momentum (qT) distributions of Drell-Yan muon and electron pairs in the Z-boson mass region (60<M(ll)<120 GeV) are reported. The results are obtained using a data sample of proton-proton collisions at a center-of-mass energy of 7 TeV, collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 36 inverse picobarns.
