QCD form factors

  1. Jul 1, 2008 #1
    Dear friends, i was working on a hadronic decays. It appears that one has to calculate form factors. These form factors involve some very complex numerical integration. I would like to know if there are some packages available for calculating these form factors.

    which form factors more specifically ? If you need all possible of them, it's going to be difficult :smile: Some of them are fairly (or very) well known.

    I was working on semileptonic B decays.

    There are some data on that, such as :
    Measurements of the B to D* Form Factors Using the Decay B0 --> D* e nu_e

    There are model calculations such as
    Form Factors for Exclusive Semileptonic $B$--Decays
    but this may be old. A paper giving references to B-FFs :
    A Study of Exclusive Charmless Semileptonic B Decays and Extraction of |V_{ub}| at CLEO
    Another, older :
    Measurement of Exclusive $B \to X_u \ell \nu$ Decays with $D^{(*)} \ell \nu$ Decay Tagging
    They also both point to lattice calculations.

    If your goal is to make a new calculation, holographic is fancy lately :smile:
