Dispersive construction of two-loop amplitudes
Karol Kampf, Marc Knecht, Jiri Novotny +1
We present and develop a general dispersive framework allowing us to construct representations of the amplitudes for the processes , , valid at the two-loop level i…
Determination of the and quark masses from decay
Martin Zdrahal
For a precise determination of the m_u and m_d quark masses, it is useful to combine isospin symmetric results of lattice or sum rules QCD techniques with some isospin breaking stu…
Dispersive representation of K -> 3 pi amplitudes and cusps
Karol Kampf, Marc Knecht, Jiri Novotny +1
The NA48/2 collaboration has shown clear experimental evidence for a cusp in the data for K -> pi pi^0 pi^0. This effect can be used to extract information on the pi-pi scattering…
Dispersive Approach to Chiral Perturbation Theory
M. Zdrahal, J. Novotny
We generalise the reconstruction theorem of Stern, Sazdjian, and Fuchs based on the dispersion relations to the case of the (2 -> 2) scattering of all the pseudoscalar octet mesons…
