“…The so-called kaonic 'helium puzzle' was solved by the E570 experiment at KEK [14], confirmed also by the SIDDHARTA experiment [15,16]. More recent and precise measurements have been performed at J-PARC by E62 [17], using a liquid helium target, and by the SIDDHARTA-2 collaboration, employing a gaseous one [18,19].…”

In this paper we present the results of a new kaonic helium-4 measurement with a 1.37 g/l gaseous target by the SIDDHARTA-2 experiment at the DAΦNE collider. We measured, for the first time, the energies and yields of three transitions belonging to the M-series. Moreover, we improved by a factor about three, the statistical precision of the 2p level energy shift and width induced by the strong interaction, obtaining the most precise measurement for gaseous kaonic helium, and measured the yield of the Lα transition at the employed density, providing a new experimental input to investigate the density dependence of kaonic atoms transitions yield.

“…33,34 A TES is a thermometer that measures temperature change after X-ray absorption by the sensor. The TES detector is a NIST system configuration optimized for 6 keV, 35 which has been used to detect kaonic atoms 36 and muonic atoms. 37,38 We demonstrated that the TES spectrometer with 240 pixels is operated simultaneously with an energy resolution of 4 eV at 6 keV at a rate of 1–10 cps per pixel.…”
