Here A, B, and C are operators; W C (x − y) are c-number functions (Wilson coefficients), singular when |x − y| → 0, that can be computed, for example, in perturbation theory. Dimensional analysis tells us that the leading contribution for y → x is due to the operators C’s in Eq. (1) that have the lowest dimension. Notice that the OPE is an operator relation and therefore, for any matrix elemen...

A bstract We study scattering amplitudes in the shadow conformal primary basis, which satisfies same defining properties as original basis and has many advantages over it. The celestial exhibit locality manifestly on sphere, behave like correlation functions field theory under operator product expansion (OPE) limit. OPE limits for three-point amplitude, general 2 ? n ? from a certain class of F...

La Operación Propaganda Exterior (OPE, 1958-‍1961) fue una operación de propaganda secreta del franquismo intermedio orientada a mejorar la imagen régimen en el exterior, principalmente EE. UU., ante contexto previo bloqueo internacional España como antiguo aliado fascista y dictadura. También se orientó vigilar moldear opinión pública española recurriendo los modernos métodos política. Este ar...

Using the ambitwistor string, we complete list of celestial operator product expansion (OPE) coefficients for supersymmetric theories. This uses string worldsheet conformal field theory to dynamically generate OPE maximally gauge theory, as well gravity and Einstein-Yang-Mills theories, including all helicity orientation configurations. extends previous purely bosonic results [T. Adamo et al., ...

A total of 65 blood samples collected from Holstein cattle were employed for DNA extraction. Genomic DNA were amplified by means of random amplified polymorphic DNA (RAPD). One hundred and one random primers (Operon kits OPAA, OPAO, OPAV, OPC, OPE and OPA-06) were used for polymerase chain reactions (PCR). The PCR products were size fractionated by means of electrophoresis in agarose gel, trans...

Inclusive semileptonic B → Xc l ν̄ decay offers the opportunity to measure the CKM parameter |Vcb| and the bottom quark mass from experiment. . Experimental studies of moments of the differential decay spectra of B → Xc l ν̄ , combined with a measurement of the total inclusive decay rate, allow the extraction of these parameters to occur with high precision. The idea is that sufficiently inclusiv...

We present OPE predictions for the hadronic mass and q2 moments in inclusive semileptonic charmless B decays, with a lower cut on the charged lepton energy and an upper cut on the hadronic invariant mass. We include non-perturbative corrections through O(1/mb ) and perturbative contributions through O(α 2 sβ0). We also investigate the range of the cut on the hadronic mass for which the local OP...
