Experimental study of the $\gamma p \rightarrow K^{0}\Sigma^{+}$, $\gamma n \rightarrow K^{0} \Lambda$, and $\gamma n \rightarrow K^{0} \Sigma^{0}$ reactions at the Mainz Microtron
Abstract. This work measured $\mathrm{d}\sigma/\mathrm{d}\Omega$ d σ / d Ω for neutral kaon photoproduction reactions from threshold up to a c.m. energy of 1855MeV, focussing specifically on the $\gamma p\rightarrow K^0\Sigma^+$ γ p → K 0 Σ + , $\gamma n\rightarrow K^0\Lambda$ γ n → K 0 Λ , and $\gamma n\rightarrow K^0 \Sigma^0$ γ n → K 0 Σ 0 reactions. Our results for $\gamma n\rightarrow K^0 \Sigma^0$ γ n → K 0 Σ 0 are the first-ever measurements for that reaction. These data will provide insight into the properties of $N^{\ast}$ N * resonances and, in particular, will lead to an improved knowledge about those states that couple only weakly to the $\pi N$ π N channel. Integrated cross sections were extracted by fitting the differential cross sections for each reaction as a series of Legendre polynomials and our results are compared with prior experimental results and theoretical predictions.

1. Abstract The production of Z boson pairs in proton–proton ( $${\mathrm{p}} {\mathrm{p}}$$ p p ) collisions, $${{\mathrm{p}} {\mathrm{p}} \rightarrow ({\mathrm{Z}}/\gamma ^*)({\mathrm{Z}}/\gamma ^*) \rightarrow 2\ell 2\ell '}$$ p p → ( Z / γ ∗ ) ( Z / γ ∗ ) → 2 ℓ 2 ℓ ′ , where $${\ell ,\ell ' = {\mathrm{e}}}$$ ℓ , ℓ ′ = e or $${{\upmu }}$$ μ , is studied at a center-of-mass energy of 13 $$\,\text {TeV}$$ TeV with the CMS detector at the CERN LHC. The data sample corresponds to an integrated luminosity of 137 $$\,\text {fb}^{-1}$$ fb - 1more »
2. A bstract Using a data sample of 980 fb − 1 collected with the Belle detector at the KEKB asymmetric-energy e + e − collider, we study the processes of $${\Xi}_c^0\to \Lambda {\overline{K}}^{\ast 0}$$ Ξ c 0 → Λ K ¯ ∗ 0 , $${\Xi}_c^0\to {\Sigma}^0{\overline{K}}^{\ast 0}$$ Ξ c 0 → Σ 0 K ¯ ∗ 0 , and $${\Xi}_c^0\to {\Sigma}^{+}{K}^{\ast -}$$ Ξ c 0 → Σ + K ∗ − for the first time.

3. A bstract The p T -differential production cross sections of prompt and non-prompt (produced in beauty-hadron decays) D mesons were measured by the ALICE experiment at midrapidity ( | y | < 0 . 5) in proton-proton collisions at $$\sqrt{s}$$ s = 5 . 02 TeV. The data sample used in the analysis corresponds to an integrated luminosity of (19 . 3 ± 0 . 4) nb − 1 . D mesons were reconstructed from their decays D 0 → K − π + , D + → K − π + π + , and $${\mathrm{D}}_{\mathrm{s}}^{+}\tomore » 4. Abstract A measurement of the$$ B_{s}^{0} \rightarrow J/\psi \phi $$B s 0 → J / ψ ϕ decay parameters using$$ 80.5\, \mathrm {fb^{-1}} $$80.5 fb - 1 of integrated luminosity collected with the ATLAS detector from 13$$\text {Te}\text {V}$$Te proton–proton collisions at the LHC is presented.

A bstract In this paper, we explore the impact of extra radiation on predictions of$$ pp\to \mathrm{t}\overline{\mathrm{t}}\mathrm{X},\mathrm{X}=\mathrm{h}/{\mathrm{W}}^{\pm }/\mathrm{Z} $$pp → t t ¯ X , X = h / W ± / Z processes within the dimension-6 SMEFT framework. While full next-to-leading order calculations are of course preferred, they are not always practical, and so it is useful to be able to capture the impacts of extra radiation using leading-order matrix elements matched to the parton shower and merged. While a matched/merged leading-order calculation for$$ \mathrm{t}\overline{\mathrm{t}}\mathrm{X}  t t ¯ X is not expected to reproduce themore »
