Observation of charge–parity symmetry breaking in baryon decays

The LHCb experiment at CERN has observed significant asymmetries between the decay rates of the beauty baryon and its CP-conjugated antibaryon, thus demonstrating CP violation in baryon decays.

Switchable narrow nonlocal conducting polymer plasmonics

Conducting polymer plasmonics provides tuneability but weak low-quality resonances which limit practical applications. Here, authors induce collective lattice resonances of PEDOT nanoantenna arrays, enabling intense and switchable nano-optical resonances with quality factors improved up to 10 times.

Combining ultrahigh index with exceptional nonlinearity in resonant transition metal dichalcogenide nanodisks

Using the 3R phase of molybdenum disulfide nanodisks with various radii, more than 100-fold enhancement of second-harmonic generation can be obtained in a single resonant nanodisk compared with an unpatterned flake of the same thickness.

Ultrathin 3R-MoS₂ metasurfaces with atomically precise edges for efficient nonlinear nanophotonics

Dielectric metasurfaces with strong nonlinearities hold promise for integrated nanophotonics and quantum technologies, yet their fabrication is hindered by material-dependent challenges and limited material choices with second-order optical nonlinearities. Here, the authors employ top-down lithography and anisotropic wet etching to fabricate atomically precise, ultrathin metasurfaces highly efficient for second-harmonic generation.

Observation of the rare B_s⁰ →µ⁺µ⁻ decay from the combined analysis of CMS and LHCb data

Combined analysis of proton-proton collision data from the Large Hadron Collider at CERN by the CMS and LHCb collaborations leads to the observation of the extremely rare decay of the strange B meson into muons; the result is compatible with the standard model of particle physics, and does not show any signs of new physics, such as supersymmetry.

Precise determination of the \(B_{\mathrm{s}}^0\)–\(\overline B_{\mathrm{s}}^0\) oscillation frequency

The LHCb collaboration reports an improved measurement of the oscillation frequency of mesons consisting of a bottom quark and strange quark, which is then combined with previous results.

Study of the doubly charmed tetraquark \({{{{{{\rm{T}}}}}}}_{{{{{{\rm{c}}}}}}{{{{{\rm{c}}}}}}}^{+}\)

The existence and properties of tetraquark states with two heavy quarks and two light antiquarks have been widely debated. Here, the authors use a unitarized model to study the properties of an exotic narrow state compatible with a doubly charmed tetraquark.

Test of lepton universality in beauty-quark decays

The Large Hadron Collider beauty collaboration reports a test of lepton flavour universality in decays of bottom mesons into strange mesons and a charged lepton pair, finding evidence of a violation of this principle postulated in the standard model.

Measurement of matter–antimatter differences in beauty baryon decays

CP violation has deep implications for particle physics and cosmology. Previously observed only in meson decays, signs of CP violation have now been spotted in baryon decays by analysing the proton–proton collision data from the LHCb detector.

Determination of the quark coupling strength |V_ub| using baryonic decays

The accurate determination of quark mixing parameters is essential for the understanding of the Standard Model. The LHCb collaboration now reports the coupling strength of the b quark to the u quark through the measurement of a baryonic decay mode.
