We measure a branching fraction $\mathcal{B}(B^0 \rightarrow \pi^0 \pi^0) = (1.38 \pm 0.27 \pm 0.22) \times 10^{-6}$ and a $\it CP$ asymmetry $\mathcal{A}_{\rm CP}(B^0 \rightarrow \pi^0 \pi^0) = 0.14 \pm 0.46 \pm 0.07$, where the first uncertainty is statistical and the second is systematic..

A galactic breeze origin for the Fermi bubbles emission [arXiv:2207.09189] The origin of the Fermi bubbles, which constitute two gamma-ray emitting lobes above and below the Galactic plane, remains unclear. The possibility that this Fermi bubbles gamma-ray emission originates from hadronic cosmic rays advected by a subsonic Galactic outflow, or breeze, is here explored.

B. ; Bangale, P. ; et al VERITAS and Fermi-LAT Constraints on the Gamma-Ray Emission from Superluminous Supernovae SN2015bn and SN2017egm [arXiv:2302.06686] The astrophysical journal / 1 945(1), 30 (2023) [10.3847/1538-4357/acb7e6]   Superluminous supernovae (SLSNe) are a rare class of stellar explosions with luminosities ∼ 10–100 times greater than ordinary core-collapse supernovae. One popular model to explain the enhanced optical output of hydrogen-poor (Type I) SLSNe invokes energy injection from a rapidly spinning magnetar.

Tau identification algorithms and study of the CP structure of the Yukawa coupling between the Higgs boson and tau leptons in CMS [DESY-THESIS-2023-005] Hamburg : Verlag Deutsches Elektronen-Synchrotron DESY, DESY-THESIS 191 pp. (2023) [10.3204/PUBDB-2023-01292] = Dissertation, Universität Hamburg, 2023   The measurement of the CP properties of the Yukawa coupling of the Higgs boson to τleptons is presented. The data set used for the analysis is collected by the CMS experiment atthe LHC during the Run 2 data-taking period in proton-proton collisions at √s = 13 TeV andcorresponds to an integrated luminosity of 137 fb−1.
