论文摘要
我们介绍了我们的项目的状态,以计算$ d \至π\ellν$,$ d \ to k \ellν$和$ d_s \ to k \ellν$ semeptonic formal formains for in toun wall for for toun wall pall for in toun wall formions。我们的计算是使用RBC/UKQCD的一组2+1个风味域壁费米恩和Iwasaki仪表集合进行的。我们计划计算涵盖完整的,物理允许的运动范围的三点功能。鉴于信号的衰减速度快于噪声,因此明确,可靠地提取基态对于成功至关重要。我们在几个可能的$ 2 \ times 2 $操作员群中包括对对角线化的分析,并找到尺寸的固定墙壁和$ \ mathbb {z} \ left(2 \右)$ wall源以零和非零动量可接受。对于第一个合奏,给出了半雌科形式因素的初始结果。
We present the status of our project to calculate $D \to π\ell ν$, $D \to K \ell ν$ and $D_s \to K \ell ν$ semileptonic form factors using domain wall fermions for both heavy and light quarks. Our computations are performed using RBC/UKQCD's set of 2+1 flavour domain wall fermion and Iwasaki gauge field ensembles. We plan to calculate three-point functions covering the full, physically allowed kinematic range. Given that the signal decays faster than the noise, unambiguously and reliably extracting the ground state is critical for success. We include an analysis of operator diagonalisation within several possible $2 \times 2$ operator bases and find an admixture of gauged fixed wall and $\mathbb{Z} \left( 2 \right)$ wall sources to be acceptable at both zero and non-zero momentum. Initial results for semileptonic form factors are presented for first ensembles.
