Strongly vs. weakly coupled in-medium showers: energy stopping in large-Nf QED / Arnold, Peter (Virginia U.) ; Elgedawy, Omar (Virginia U. ; South China Normal U.) ; Iqbal, Shahin (Quaid-i-Azam U. ; CERN)
Inside a medium, showers originating from a very high-energy particle may develop via medium-induced splitting processes such as hard bremsstrahlung or pair production. During shower development, two consecutive splittings sometimes overlap quantum mechanically, so that they cannot be treated independently. [...]

Measurement of the effective leptonic weak mixing angle / LHCb Collaboration
Using pp collision data at s=13~TeV, recorded by the LHCb experiment between 2016 and 2018 and corresponding to an integrated luminosity of 5.4~fb1, the forward-backward asymmetry in the ppZ/γμ+μ process is measured. The measurement is carried out in ten intervals of the difference between the muon pseudorapidities, within a fiducial region covering dimuon masses between 66 and 116 GeV, muon pseudorapidities between 2.0 and 4.5 and muon transverse momenta above 20 GeV. [...]

Measurement of CP violation observables in D+KK+π+ decays / LHCb Collaboration
A search for violation of the charge-parity (CP) symmetry in the D+KK+π+ decay is presented, with proton-proton collision data corresponding to an integrated luminosity of 5.4 fb1, collected at a center-of-mass energy of 13 TeV with the LHCb detector. A novel model-independent technique is used to compare the D+ and D phase-space distributions, with instrumental asymmetries subtracted using the D+sKK+π+ decay as a control channel. [...]

Study of the rare decay J/ψμ+μμ+μ / LHCb Collaboration
The rare electromagnetic J/ψμ+μμ+μ decay is observed with a significance greatly exceeding the discovery threshold, using proton-proton collision data collected by the LHCb experiment during 2016--2018 at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.4fb1. The rate of this decay is measured relative to that of the J/ψμ+μ mode. [...]

Observation of muonic Dalitz decays of χb mesons and precise spectroscopy of hidden-beauty states / LHCb Collaboration
The decays of the χb1(1P), χb2(1P), χb1(2P) and χb2(2P) mesons into the Υ(1S)μ+μ final state are observed with a high significance using proton-proton collision data collected with the LHCb detector and corresponding to an integrated luminosity of 9fb1. The newly observed decays together with the Υ(2S)Υ(1S)π+π and Υ(3S)Υ(2S)π+π decay modes are used for precision measurements of the mass and mass splittings for the hidden-beauty states..

Softening of the hypertriton transverse momentum spectrum in heavy-ion collisions / Liu, Dai-Neng (Fudan U., Shanghai) ; Ko, Che Ming (Texas A-M) ; Ma, Yu-Gang (Fudan U., Shanghai) ; Mazzaschi, Francesco (Bari U. ; INFN, Bari) ; Puccio, Maximiliano (CERN) ; Shou, Qi-Ye (Fudan U., Shanghai) ; Sun, Kai-Jia (Fudan U., Shanghai) ; Wang, Yuan-Zhe (Fudan U., Shanghai)
Understanding the properties of hypernuclei helps to constrain the interaction between hyperon and nucleon, which is known to play an essential role in determining the properties of neutron stars. Experimental measurements have suggested that the hypertriton (Λ3H), the lightest hypernucleus, exhibits a halo structure with a deuteron core encircled by a Λ hyperon at a distance of about 10 fm.
