abstract = {In this paper, we introduced a new class of weak Hardy spaces, denoted by  Hbp,∞, and provided an analysis of their atomic decomposition. As an application, we established the boundedness of Calderón-Zygmund operators (CZOs) from  Hp to  Hbp,∞ including cases at the critical exponent   p=nn+δ,where  δ represents the regularity index of the distributional kernel. Moreover, the boundedness of CZOs from  Hp,∞ to  Hbp,∞ was demonstrated for   nn+δ&lt;p≤1.}
