Dispersive sum rules in AdS2

چکیده
Dispersion relations for S-matrices and CFT correlators translate UV consistency into bounds on IR observables. In this note, we construct dispersive sum rules 1D CFTs. We use them to prove higher-derivative couplings in weakly-coupled non-gravitational EFTs AdS$_2$. At the leading order bulk-point limit, agree with flat-space result. compute universal effect of finite AdS radius bounds. Along way, give an explicit formula anomalous dimensions general contact Witten diagrams

Dispersive Methods and QCD Sum Rules for γ γ Collisions
It has been shown, in the case of meson photoproduction, that the power-law falloff of these reactions can be described by lowest order (real) sum rules, at moderate momentum transfer. The phases of these processes, in this regime, are usually thought to be non-perturbative. In a sum rule framework, however, they can possibly be described by radiative corrections to the hadronic spectral densit...
متن کاملDecays in QCD Sum Rules
The form factors relevant to Bq → D∗ q(J = 1−)lν (q = s, d, u) decays are calculated in the framework of the three point QCD sum rules approach. The heavy quark effective theory prediction of the form factors as well as 1/mb corrections to those form factors are obtained. A comparison of the results for the ratio of form factors at zero recoil limit and other values of q2 with the predictions o...
متن کاملVertex in QCD Sum Rules
The J/ψDD form factor is evaluated in a QCD sum rule calculation for both D and J/ψ off-shell mesons. We study the double Borel sum rule for the three point function of two pseudoscalar and one vector meson current. We find that the momentum dependence of the form factors is different if the D or the J/ψ meson is off-shell, but they lead to the same coupling constant in the J/ψDD vertex. The co...
متن کاملCouplings in QCD Sum Rules
We calculate the coupling constants, gπNS11 and gηNS11 , using QCD sum rules in the presence of an external meson field. A covariant derivative is introduced within the S11 interpolating field so that in the nonrelativistic limit the field dominantly reduces to two quarks in the s-wave state and one quark in the p-wave state. Our result for the couplings obtained by further making use of the so...
متن کاملParton Model Sum Rules
This review article discusses the experimental and theoretical status of various Parton Model sum rules. The basis of the sum rules in perturbative QCD is discussed. Their use in extracting the value of the strong coupling constant is evaluated and the failure of the naive version of some of these rules is assessed. This work was supported by the Director, Office of Energy Research, Office of H...
