Chiral perturbation theory for t ̃ rpnt , t ̃ K
نویسنده
چکیده
We use heavy vector meson SU~2!L3SU~2!R chiral perturbation theory to predict differential decay distributions for t→rpnt and t→K* pnt in the kinematic region where pV•pp/mV ~here V5r or K*! is much smaller than the chiral symmetry-breaking scale. We also predict the rate for t→vpnt in this region ~now V5v!. Comparing our prediction with experimental data, we determine one of the coupling constants in the heavy vector meson chiral Lagrangian.

We test the one-loop chiral perturbation theory formula on unquenched lattice data of pseudoscalar meson decay constants. The chiral extrapolation including the effect of the chiral logarithm is attempted and its uncertainty is discussed.

The charged kaon decay channel K l3γ allows for studies of direct CP violation, possibly due to non-standard mechanisms, with the help of T -odd correlation variables. In order to be able to extract a CP -violating signal from experiment, it is necessary to understand all possible standard model phases that also produce T -odd asymmetries. We complement earlier studies by considering strong int...

We present the ingredients necessary for the determination of physical K → ππ decay amplitudes for ∆I = 3/2 transitions, from lattice simulations at unphysical kinematics and the use of chiral perturbation theory at next-to-leading order. In particular we derive the expressions for the matrix elements I=2〈 ππ|OW |K〉, where OW is one of the operators appearing in the ∆S = 1 weak Hamiltonian, in ...
متن کاملChiral corrections to kaon-nucleon scattering lengths
We calculate the threshold T-matrices of kaon-nucleon and antikaon-nucleon scattering to one loop order in SU(3) heavy baryon chiral perturbation theory. To that order the complex-valued isospin-1 KN threshold T-matrix can be successfully predicted from the isospin-0 and 1 KN threshold T-matrices. As expected perturbation theory fails to explain the isospin-0 KN threshold T-matrix which is comp...
