CHY Loop Integrands from Holomorphic Forms

Humberto Gomez, Sebastian Mizera, Guojun Zhang

Recently, the Cachazo-He-Yuan (CHY) approach for calculating scattering amplitudes has been extended beyond tree level. In this paper, we introduce a way of constructing CHY integr…

Analysis of the nonleptonic charmonium modes $B_{s}^{0} \to J / ψ f_{2}^{'} (1525)$ and $B_{s}^{0} \to J / ψ K^{+} K^{-}$

Cesar A. Morales, Nestor Quintero, Carlos E. Vera +1

In this work, we present an analysis of the nonleptonic charmonium modes $B_{s}^{0} \to J / ψ f_{2}^{'} (1525)$ and $B_{s}^{0} \to J / ψ K^{+} K^{-}$ . Within the framework of the factorization appr…

CHY-Graphs on a Torus

Carlos Cardona, Humberto Gomez

Recently, we proposed a new approach using a punctured Elliptic curve in the CHY framework in order to compute one-loop scattering amplitudes. In this note, we further develop this…

Cross-ratio Identities and Higher-order Poles of CHY-integrand

Carlos Cardona, Bo Feng, Humberto Gomez +1

The evaluation of generic Cachazo-He-Yuan(CHY)-integrands is a big challenge and efficient computational methods are in demand for practical evaluation. In this paper, we propose a…

Constraints on lepton number violating short-range interactions from $∣Δ L ∣ = 2$ processes

Nestor Quintero

In this work we study the short-range contributions that induce effective lepton number violating (LNV) interactions. We obtain a full set of constraints on the effective short-ran…
