We explain how the Swampland criteria combined with observational data and in particular a small dark energy, leads to the prediction of a single mesoscopic dimension of length in the micron range. We also explain how this can lead to a unification of cosmological and electroweak hierarchies.
In this talk we will revisit supergravity models with dark
matter candidate particles like neutralino and gravitino.
Moreover, we will discuss the possibility that primordial black
holes play the role of the dark matter of the Universe.
The standard model of cosmology is based on the assumption that the universe is (statistically) isotropic and homogeneous. The dipole anisotropy of the CMB must then be attributed to our peculiar motion, due to local inhomogeneity, wrt the cosmic rest frame in which the CMB looks isotropic. If so, there should be a corresponding dipole in the skymap of high redshift sources. Using catalogues...
We present the motivation for the celestial holography program, recent progress, and ongoing questions!
I discuss a framework in which a low-energy effective Chern-Simons (CS) modification of General relativity emerges as a viable cosmological model from string theory. Condensation of CP-violating primordial gravitational waves can lead to non-trivial CS anomaly condensates, which drive inflation without external inflaton fields, of running vacuum model type.
The string-model independent axion...
The MicroBooNE collaboration recently released a series of measurements aimed at investigating the nature of the excess of low energy electromagnetic interactions observed by the MiniBooNE collaboration. In this talk, we will present the latest results from both a search of single photons in MicroBooNE, as well as a series of three independent analyses leveraging different reconstruction...
I review the deviations from the Standard Model predictions observed in low energy precision measurements. This includes the anomalous magnetic moment of the muon, semi-lepton B meson decays, the Cabibbo Angle anomaly, the mass of the W boson and searches for very high-energetic lepton pairs. I then discuss the implications of these anomalies for possible extensions of the Standard Model.
I discuss the use of Genetic Algorithms (GAs) as a search method in string theory. I will describe work showing that, despite intense recent developments in more conventional machine learning methods, GAs remain remarkably effective. Indeed comparison with Reinforcement Learning (RL) shows them to be in some respects superior. I also discuss how GAs and RL can be used in conjunction to make...
We discuss various approaches to the flavour problem of the Standard Model, including the LFU violation anomalies in B decays, in which the Yukawa couplings may be determined by symmetry or anarchy and may be renormalizable or effective. If the Yukawa couplings are effective, in principle the flavour scale can be anywhere from the Planck scale to the Electroweak scale, where SUSY/GUTs suggest...
Studying the properties of the Higgs boson can be an important window to explore the physics beyond the Standard Model. In this work, we present studies on the implications of the Higgs precision measurements at future Higgs Factories on various types of two Higgs Doublet Models. We perform a global fit to various Higgs search channels to obtain the 95% C.L. constraints on the model parameter...
The Sachdev-Ye-Kitaev (SYK) model is a quantum mechanical model that is strongly interacting, chaotic and solvable. It is known to have a gravity dual and exhibit black hole
physics. Recently, a sparse version of SYK was proposed. These sparse SYK models can be obtained by randomly pruning the couplings of the all-to-all SYK or defined by random regular hypergraphs. The sparsity makes...
