We present a constrained analysis of the valence transversity Parton Distribution Functions from dihadron production in semi-inclusive DIS. While usual extractions of the transversity distributions rely explicitly on the fulfillment of the Soffer bound, the present analysis releases that restriction to implement further constraints through the method of Lagrange multipliers. The results are quantitatively comparable to previous analyses in the kinematical range of data; the qualitative impact translates into an increased flexibility in the functional form.

二面体生产的价态横向分布的约束拟合

我们提出了半包容性DIS中二面体生产的价态横向Parton分布函数的约束分析。虽然通常的横向分布提取明显依赖于Soffer边界的满足，但本分析释放了该约束，以通过拉格朗日乘数法实现进一步的约束。在数据的运动学范围内，结果与先前的分析在数量上可比；定性影响转化为功能形式上增加的灵活性。
