Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on the effects of climate change on the risk of transmission of foodborne pathogens

open access: yesFood Risk Assess Europe, Volume 3, Issue 3, July 2025.
Abstract The Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) has carried out an updated review of the scientific evidence on the influence of climate change on the transmission of foodborne pathogens. This global phenomenon represents an emerging threat to food safety and public health, since alterations in weather ...

Bosonic construction of superstring theory and related topics [PDF]

open access: yes, 2002
This thesis splits into two parts. In the first part we introduce a bosonic construction of the ten-dimensional fermionic theories. This construction relies on a consistent truncation procedure which can produce fermions out of bosons. We illustrate this

SL(2, ℤ) dualities of boundary conditions in Abelian M2-brane SCFTs

open access: yesJournal of High Energy Physics
We propose SL(2, ℤ) dualities of supersymmetric boundary conditions in the three-dimensional supersymmetric field theories describing a semi-infinite M2-brane terminating on M5-branes. Specifically, we present dualities of boundary conditions for Abelian

Celestial Topology, Symmetry Theories, and Evidence for a NonSUSY D3‐Brane CFT

open access: yesFortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract Symmetry Theories (SymThs) provide a flexible framework for analyzing the global categorical symmetries of a D$D$‐dimensional QFTD$\text{QFT}_{D}$ in terms of a (D+1)$(D+1)$‐dimensional bulk system SymThD+1$\text{SymTh}_{D+1}$. In QFTs realized via local string backgrounds, these SymThs naturally arise from dimensional reduction of the linking

One-loop phenomenology in brane models [PDF]

open access: yes, 2005
Particular examples of one-loop string effects are explored in the context of brane-based realizations of the Standard Model. We firstly examine the consequences of a phenomenon known as Kinetic Mixing, which couples hidden U(1) gauge factors to visible ...

Nilpotent orbits and the Coulomb branch of T σ (G) theories: special orthogonal vs orthogonal gauge group factors

open access: yesJournal of High Energy Physics, 2017
Coulomb branches of a set of 3d N $$ \mathcal{N} $$ = 4 supersymmetric gauge theories are closures of nilpotent orbits of the algebra son $$ \mathfrak{so}(n) $$.

A Goldstone theorem for continuous non-invertible symmetries

open access: yesJournal of High Energy Physics, 2023
We study systems with an Adler-Bell-Jackiw anomaly in terms of non-invertible symmetry. We present a new kind of non-invertible charge defect where a key role is played by a local current operator localized on the defect.

T‐Symmetry in String Geometry Theory

open access: yesAdvances in High Energy Physics, Volume 2025, Issue 1, 2025.
String geometry theory is one of the candidates of nonperturbative formulation of string theory. In this paper, we have shown that dimensionally reduced string geometry theories have what we call T‐symmetry. In the case of the dimensional reduction in space‐like directions, the T‐symmetry transformation gives the T‐dual transformation between the Type ...

Aspects of D-brane inflation [PDF]

open access: yes, 2013
Inflation has been suggested as a solution to cosmological problems but it ultimately needs to be derived from a fundamental theory such as string theory.
