Proton-proton interactions resulting in final states with two photons are studied in a search for the signature of flavor-changing neutral current interactions of top quarks (t) and Higgs bosons (H). The analysis is based on data collected at a center-of-mass energy $\sqrt{s}=13~\mathrm{TeV}$ with the CMS detector at the LHC, corresponding to an integrated luminosity of $137~\mathrm{fb}^{-1}$. No significant excess above the background prediction is observed. Upper limits on the branching fractions ($\mathcal B$) of the...

BNL-RHIC. Elliptic flow ($v_{2}$) values for identified particles at midrapidity in Au + Au collisions measured by the STAR experiment in the Beam Energy Scan at the Relativistic Heavy Ion Collider at $\sqrt{s_{NN}}$ = 7.7-62.4 GeV are presented for three centrality classes. The centrality dependence and the data at $\sqrt{s_{NN}}$ = 14.5 GeV are new. Except at the lowest beam energies we observe a similar relative $v_{2}$ baryon-meson splitting for all centrality classes which is...

CERN-LHC, ATLAS. A search for the Higgs boson decaying into a photon and a pair of electrons or muons with an invariant mass $m_{\ell\ell} < 30$ GeV is presented. The analysis is performed using 139 fb$^{-1}$ of proton-proton collision data, produced by the LHC at a centre-of-mass energy of 13 TeV and collected by the ATLAS experiment. Evidence for the $H \rightarrow \ell \ell \gamma$ process is found with a significance of 3.2$\sigma$ over the...

A2 at MAMI. The $\gamma p \to \pi^0 p$ reaction was studied at laboratory photon energies from 425 to 1445 MeV with a transversely polarized target and a longitudinally polarized beam. The beam-target asymmetry F was measured for the first time and new high precision data for the target asymmetry T were obtained. The systematic uncertainty is dominated by the determination of the degree of proton polarization (4%), the degree of photon beam polarization (2%),...

Global polarization of $\Xi$ and $\Omega$ hyperons has been measured for the first time in Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV. The measurements of the $\Xi^-$ and $\bar{\Xi}^+$ hyperon polarization have been performed by two independent methods, via analysis of the angular distribution of the daughter particles in the parity violating weak decay $\Xi\rightarrow\Lambda+\pi$, as well as by measuring the polarization of the daughter $\Lambda$-hyperon, polarized via polarization transfer from its parent. The polarization,...

CERN-LHC, ATLAS. Limits on pair production of Higgs bosons in the final state with two bottom quarks plus two photons. The search is based on 139 $fb^{-1}$ of pp collisions at $\sqrt{s}$ = 13 TeV recorded by the ATLAS detector at the CERN Large Hadron Collider. Data include exactly two b-tagged jets with a 77% working point and two well-identified isolated photons. The search is sensitive to both resonant and nonresonant production of Higgs boson...

The associated production of a $\mathrm{W}$ and a $\mathrm{Z}$ boson is studied in final states with multiple leptons produced in proton-proton ($\mathrm{p}$$\mathrm{p}$) collisions at a centre-of-mass energy of $13~\mathrm{TeV}$ using $137~\mathrm{fb}^{-1}$ of data collected with the CMS detector at the LHC. A measurement of the total inclusive production cross section yields $\sigma_{\textrm{tot}}(\mathrm{pp}\to\mathrm{WZ}) = 50.6 \pm 0.8 (\textrm{stat}) \pm 1.5 (\textrm{syst}) \pm 1.1 (\textrm{lum}) \pm 0.5 (\textrm{theo})~\mathrm{pb}$. Measurements of the fiducial and differential cross sections for...

A measurement of the inclusive b-jet production cross section is presented in pp and p-Pb collisions at $\sqrt{s_{\mathrm{NN}}}~=0.5~$TeV, using data collected with the ALICE detector at the LHC. The jets were reconstructed in the central rapidity region $|\eta|<0.5$ from charged particles using the anti-$k_{\rm T}$ algorithm with resolution parameter $R=0.4$. Identification of b jets exploits the long lifetime of b-hadrons, using the properties of secondary vertices and impact parameter distributions. The $p_\mathrm{T}$-differential inclusive production cross...

The production of prompt $\rm D^{0}$, $\rm D^{+}_{s}$, and $\rm \Lambda_{c}^{+}$ hadrons, and their ratios, $\rm D^{+}_{s} / D^{0}$ and $\rm \Lambda_{c}^{+} / D^{0}$, are measured in proton--proton collisions at $\sqrt{s}=13$~TeV at midrapidity ($|y|<0.5$) with the ALICE detector at the LHC. The measurements are performed as a function of the charm-hadron transverse momentum ($p_{\rm T}$) in intervals of charged-particle multiplicity, measured with two multiplicity estimators covering different pseudorapidity regions. While the strange to non-strange $\rm...

Measurement by the STAR experiment at RHIC of the cold nuclear matter (CNM) effects experienced by inclusive \jpsi\ at mid-rapidity in 0-100\% \pAu\ collisions at \sqrtsNN\ = 200 GeV is presented. Such effects are quantified utilizing the nuclear modification factor, \rpa, obtained by taking a ratio of \jpsi\ yield in \pAu\ collisions to that in \pp\ collisions scaled by the number of binary nucleon-nucleon collisions. The differential \jpsi\ yield in both \pp\ and \pAu\ collisions...

The first search at the LHC for resonances decaying into a $\mathrm{W}$ and a radion boson, where the radion boson decays into two $\mathrm{W}$ bosons, is presented. The data analyzed correspond to an integrated luminosity of 138 $\mathrm{fb}^{-1}$ recorded in proton-proton collisions with the CMS detector at $\sqrt{s}$ = 13 TeV. One isolated charged lepton from a $\mathrm{W}$ boson decay is required, while the decay products of the other two $\mathrm{W}$ bosons are reconstructed as...

A search is reported for pairs of light Higgs bosons ($\mathrm{H}_1$) produced in supersymmetric cascade decays in final states with small missing transverse momentum. A data set of LHC pp collisions collected with the CMS detector at $\sqrt s=13\;\mathrm{TeV}$ and corresponding to an integrated luminosity of $137\;\mathrm{fb}^{-1}$ is used. The search targets events where both $\mathrm{H}_1$ bosons decay into $b\bar{b}$ pairs that are reconstructed as large-radius jets using substructure techniques. No evidence is found for...

A search for an extended Higgs sector, characterized by a massive resonance X decaying to a pair of spin-0 bosons $\phi$ that themselves decay to pairs of bottom quarks, is presented. The analysis is restricted to the mass ranges $m_\phi$ from 25 to 100 GeV and $m_\textrm{X}$ from 1 to 3 TeV. For these mass ranges, the decay products of each $\phi$ boson are expected to merge into a single large-radius jet. Jet substructure and...

A search for resonant Higgs boson pair production in the $b\bar{b}b\bar{b}$ final state is presented. The analysis uses 126-139 fb$^{-1}$ of $pp$ collision data at $\sqrt{s}$ = 13 TeV collected with the ATLAS detector at the Large Hadron Collider. The analysis is divided into two channels, targeting Higgs boson decays which are reconstructed as pairs of small-radius jets or as individual large-radius jets. Spin-0 and spin-2 benchmark signal models are considered, both of which correspond...
