Unveiling the Strong Force: New Insights from Kaon-Deuteron Collisions
![The study’s determination of [latex]K^{-}d[/latex] scattering lengths-achieved through a Lednický-Lyuboshits fit-aligns with existing theoretical calculations derived from SIDDHARTA and KEK experimental data, as evidenced by the correspondence between the ALICE measurement’s systematic and statistical uncertainties, represented by full and empty ellipses respectively.](https://arxiv.org/html/2602.22833v1/2602.22833v1/x2.png)
A femtoscopic analysis has yielded the first measurement of scattering parameters for kaon-deuteron interactions, providing critical data for understanding the strong nuclear force.

![A four-dimensional Markov Chain Monte Carlo analysis constrained the mass and orbital radius of quasi-periodic oscillations for stellar-mass black holes - XTE J1550-564, GRO J1655-40, GRS 1915+105, and M82 X-1 - revealing the inherent uncertainty in these parameters as defined by [latex]1\sigma[/latex] and [latex]2\sigma[/latex] confidence intervals, and highlighting the probabilistic nature of astrophysical modeling.](https://arxiv.org/html/2602.22264v1/2602.22264v1/M82_X-1_in.png)
