Double Field Theory with matter and the generalized Bergshoeff-de Roo identification

Autor: Lescano, Eric, Mirón-Granese, Nahuel

The scalar field-perfect fluid (sf-pf) correspondence shows that the energy-momentum tensor of a scalar field is in correspondence with the dynamics of a perfect fluid. In this work we generalize this concept to study the higher-derivative structure

The generalized Bergshoeff-de Roo identification II

Autor: Baron, Walter H., Marques, Diego

We recently introduced a T-duality covariant mechanism to compute all-order higher-derivative interactions in the heterotic string. Here we extend the formalism to account for a two-parameter family of corrections that also include the bosonic string

The generalized Bergshoeff-de Roo identification

Autor: Baron, Walter H., Lescano, Eric, Marques, Diego

There are two main approaches to duality covariant first order higher derivative corrections to the heterotic string, one extending the duality structure and the other deforming the gauge transformations. In this paper we introduce a framework from w

The LHCb detector has undergone a major upgrade for LHC Run 3. This Upgrade I detector facilitates operation at higher luminosity and utilises full-detector information at the LHC collision rate, critically including the use of vertex information. A
