Examining the stellar-merger origin of the blue main sequence in the open cluster NGC\,3532 with N-body simulations

Khushboo K. Rao, Sambaran Banerjee

Extended main-sequence turnoffs, extended main sequences, and split main sequences observed in the colour-magnitude diagrams of young and intermediate-age star clusters are now wid…

Running of the Electroweak Gauge Couplings from First Principles

Alessandro Conigli, Dalibor Djukanovic, Georg von Hippel +6

We present a high-precision calculation of the hadronic running of electroweak gauge couplings from first principles. Employing lattice QCD in the low-energy regime, we achieve per…

Probing nuclear interactions à la Rutherford: Insights on $^{4}$ He from $α$ scattering

F. Cappuzzello, V. Soukeras, S. Bacca +27

Nuclear interactions play a key role for the stability of atomic nuclei and stellar environments. Successful parametrization and models of these interactions, developed in the last…

Measurement of the double Dalitz decay $η \to e^{+} e^{-} e^{+} e^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

Using a data sample of $(1.0087 \pm 0.0044) \times 1 0^{10}$ $J / ψ$ events collected with the BESIII detector, we study the rare double Dalitz decay of $η \to e^{+} e^{-} e^{+} e^{-}$ …

Amplitude Analysis of the Isospin-Violating Decay $J / ψ \to γ η π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +759

Using $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, we perform the first amplitude analysis of the process $J / ψ \to γ η π^{0}$ . The decay is dominated b…

Observation of $Λ_{c}^{+} \to n π^{+} η$ and search for $Λ_{c}^{+} \to n a_{0} (980)^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +719

By analysing 6.1 $fb^{- 1}$ of data collected at center-of-mass energies between $s = 4.600$ and 4.843 $GeV$ with the BESIII detector at the BEPCII collider, we obser…
