New Physics Phenomena and F-theory GUTs

TL;DR

This paper discusses the implications of B-meson decay anomalies observed at LHCb and proposes semi-local F-theory GUT models with extra neutral gauge bosons to explain these anomalies.

Contribution

It introduces a new class of semi-local F-theory GUT models that can account for B-meson decay anomalies, linking string-inspired theories with experimental observations.

Findings

Models can explain R_K and R_K* anomalies

Proposes specific gauge bosons responsible for anomalies

Bridges string theory with particle physics experiments

Abstract

In this presentation the new physics implications of the $B$-meson decay anomalies, observed at LHCb, are discussed. In the first part of the talk a brief overview of the experimental status is presented. In the second part, a class of semi-local F-theory GUT models with additional neutral gauge bosons are proposed which are capable of accounting for the anomalous $B$-decay ratios $R_{K}$ and $R_{K^*}$
