Abstract
A new evaluation of the level shift and width of kaonic deuterium is presented based on an accurate three-body calculation, using as input a realistic antikaon-nucleon interaction constrained by the SIDDHARTA kaonic hydrogen data. The three-body Schr\"odinger equation is solved with a superposition of a large number of correlated Gaussian basis functions extending over distance scales up to several hundred fm. The resulting energy shift and width of the kaonic deuterium level are keV and keV, with estimated uncertainties at the 10% level.
