A search for cascade decays of charged sleptons and sneutrinos using final states characterized by three leptons (electrons or muons) and missing transverse momentum is presented. The analysis is based on a dataset with <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mn>140</mn><mtext> </mtext><mtext> </mtext><msup><mi>fb</mi><mrow><mo>−</mo><mn>1</mn></mrow></msup></math> of proton-proton (pp) collisions at a center-of-mass energy of <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><msqrt><mi>s</mi></msqrt><mo>=</mo><mn>13</mn><mtext> </mtext><mtext> </mtext><mi>TeV</mi></math> recorded by the ATLAS detector at the Large Hadron Collider. This paper focuses on a supersymmetric scenario that is motivated by the muon anomalous magnetic moment observation, dark-mattter relic density abundance, and electroweak naturalness. A mass spectrum involving light Higgsinos and heavier sleptons with a bino at intermediate mass is targeted. No significant deviation from the Standard Model expectation is observed. This search enables us to place stringent constraints on this model, excluding at the 95% confidence level charged slepton and sneutrino masses up to 450 GeV when assuming a lightest neutralino mass of 100 GeV and mass-degenerate selectrons, smuons and sneutrinos.

The STAR Collaboration reports precise measurements of the longitudinal double-spin asymmetry, <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><msub><mi>A</mi><mrow><mi>L</mi><mi>L</mi></mrow></msub></math>, for dijet production with at least one jet at intermediate pseudorapidity <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mrow><mn>0.8</mn><mo>&lt;</mo><msub><mrow><mi>η</mi></mrow><mrow><mtext>jet</mtext></mrow></msub><mo>&lt;</mo><mn>1.8</mn></mrow></math> in polarized proton-proton collisions at a center-of-mass energy of 200 GeV. This study explores partons scattered with a longitudinal momentum fraction (<math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mi>x</mi></math>) from 0.01 to 0.5, which are predominantly characterized by interactions between high-<math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mi>x</mi></math> valence quarks and low-<math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><mi>x</mi></math> gluons. The results are in good agreement with previous measurements at 200 GeV with improved precision and are found to be consistent with the predictions of global analyses that find the gluon polarization to be positive. In contrast, the negative gluon polarization solution from the JAM Collaboration is found to be strongly disfavored.
