چکیده
We develop crossing symmetric dispersion relations for describing 2-2 scattering of identical external particles carrying spin. This enables us to import techniques from Geometric Function Theory and study two sided bounds on low energy Wilson coefficients. consider photons, gravitons in weakly coupled effective field theories. provide general expressions the locality/null constraints. Consideration positivity absorptive part leads an interesting connection with recently conjectured weak spin dominance. also construct amplitudes locality constraints massive neutral Majorana fermions parity violating photon graviton The developed this paper will be useful considering numerical S-matrix bootstrap future.

S-matrix and crossing symmetry
An S-matrix satisying the Yang-Baxter equation with symmetries relevant to the AdS5 × S5 superstring has recently been determined up to an unknown scalar factor. Such scalar factors are typically fixed using crossing relations, however due to the lack of conventional relativistic invariance, in this case its determination remained an open problem. In this paper we propose an algebraic way to im...
متن کاملA Crossing – Symmetric Phase for AdS 5 × S 5 Strings
We propose an all-order perturbative expression for the dressing phase of the AdS5 × S string S-matrix at strong coupling. Moreover, we are able to sum up large parts of this expression. This allows us to start the investigation of the analytic structure of the phase at finite coupling revealing a few surprising features. The phase obeys all known constraints including the crossing relation and...
متن کاملThe (R,S)-symmetric and (R,S)-skew symmetric solutions of the pair of matrix equations A1XB1 = C1 and A2XB2 = C2
Let $Rin textbf{C}^{mtimes m}$ and $Sin textbf{C}^{ntimes n}$ be nontrivial involution matrices; i.e., $R=R^{-1}neq pm~I$ and $S=S^{-1}neq pm~I$. An $mtimes n$ complex matrix $A$ is said to be an $(R, S)$-symmetric ($(R, S)$-skew symmetric) matrix if $RAS =A$ ($ RAS =-A$). The $(R, S)$-symmetric and $(R, S)$-skew symmetric matrices have a number of special properties and widely used in eng...
متن کاملUpper and lower bounds of symmetric division deg index
Symmetric Division Deg index is one of the 148 discrete Adriatic indices that showed good predictive properties on the testing sets provided by International Academy of Mathematical Chemistry. Symmetric Division Deg index is defined by $$ SDD(G) = sumE left( frac{min{d_u,d_v}}{max{d_u,d_v}} + frac{max{d_u,d_v}}{min{d_u,d_v}} right), $$ where $d_i$ is the degree of vertex $i$ in graph $G$. In th...
متن کاملCrossing Numbers: Bounds and Applications
We give a survey of techniques for deriving lower bounds and algorithms for constructing upper bounds for several variations of the crossing number problem. 1 aim is to emphasize the more general results or those results which have an algorith-mic avor, including the recent results of the authors. We also show applications of crossing numbers to other areas of discrete mathematics, like discret...
