Direct measurement of the in-medium $η^{'}$ mass spectrum through the $γ γ$ decay channel

Y. Matsumura, N. Muramatsu, T. A. Hashimoto +58

We measured the invariant mass of the $η^{'} (958)$ meson through the $η^{'} \to γ γ$ decay channel to search for possible character change of $η^{'}$ in a nuclear mediu…

Measurement of the mesonic decay branch of the $K ˉ N N$ quasi-bound state

T. Yamaga, S. Ajimura, H. Asano +67

We conducted measurements of $K^{-} +^{3} He \to π Y N + N^{'}$ reactions using a $1 GeV / c$ $K^{-}$ -beam, with the objective of understanding the broad decay width of $\bar…

Measurements of high-n transitions in intermediate mass kaonic atoms by SIDDHARTA-2 at DA $Φ$ NE

F. Sgaramella, M. Tüchler, C. Amsler +38

The SIDDHARTA-2 experiment installed at the DA $Φ$ NE collider of INFN-LNF performed, for the first time, measurements of high-n transitions in intermediate mass kaonic atoms…

Pole position of $Λ (1405)$ measured in $d (K^{-}, n) π Σ$ reactions

PARC E31 Collaboration, S. Aikawa, S. Ajimura +74

We measured a set of $π^{\pm} Σ^{\mp}$ , $π^{0} Σ^{0}$ , and $π^{-} Σ^{0}$ invariant mass spectra below and above the $K ˉ N$ mass threshold in $K^{-}$ -induced reactions on deuteron. We deduced th…

Differential cross sections and photon beam asymmetries of $η$ photoproduction on the proton at $E_{γ}$ = 1.3-2.4 GeV

T. Hashimoto, T. Nam, N. Muramatsu +57

We have carried out exclusive measurements for the photoproduction of an $η$ meson from a proton target with an egg-shaped calorimeter made of BGO crystals (BGOegg) and forward cha…

Fundamental physics at the strangeness frontier at DAΦNE. Outline of a proposal for future measurements

C. Curceanu, C. Guaraldo, A. Scordo +8

The DAΦNE collider at INFN-LNF is a unique source of low-energy kaons, which was used by the DEAR, SIDDHARTA and AMADEUS collaborations for unique measurements of kaonic atoms and…
