Interpreting the spectral energy distributions (SEDs) of astrophysical objects with physically motivated models is computationally expensive. These models require solving coupled differential equations in high-dimensional parameter spaces, making traditional fitting techniques such as Markov Chain Monte Carlo or nested sampling prohibitive. [...]

A detailed understanding of water’s marvelous ability to solvate small molecules is a central theme in chemistry. In this work, we have identified twelve new partially and fully deuterated isotopologues of the hydrochloric acid dihydrate cluster, (H2O)2HCl, by chirped pulse Fourier transform microwave spectroscopy. [...]

Machine learning techniques for the solution of inverse problems have become an attractive approach in the last decade, while their theoretical foundations are still in their infancy. In this chapter we want to pursue the study of regularization properties, robustness, convergence rates, and structure of regularizers for inverse problems obtained from different learning paradigms. [...]

We derive the Regge factorization associated with Glauber pinched singularities in gapped-Hard scattering processes and shed novel light on the physical origin of the super-leading logarithms (SLL) in the gap-between-jets observable. We show that SLL series is, in fact, generated by the well-known BFKL evolution in the rapidity combined with UV renormalization of factorized low-energy matrix elements. [...]

I will consider correlation functions of five scalar BPS operators in N=4 SYM theory from various perspectives, and present recent results on their computation..

The results obtained at the LHC for constraining the trilinear Higgs self-coupling of the detected Higgs boson at about 125 GeV, $\lambda _{hhh}$, via the Higgs pair production process have significantly improved during the last years. We investigate the impact of potentially large higher-order corrections and interference effects on the comparison between the experimental results and the theoretical predictions for the pair production of the 125 GeV Higgs boson at the LHC. [...]

To address new applications in the 20–30 keV photon energy range at the European XFEL, where silicon sensors lose quantum efficiency, the AGIPD consortia has developed anAGIPD detector prototype with high-Z sensor materials. An electron-collecting version of the chip (ecAGIPD) was designed to leverage from the higher mobility and longer lifetime of electrons with respect to holes in the candidate materials: chromium-doped gallium arsenide (GaAs:Cr) and high-flux cadmium zinc telluride (CdZnTe). [...]

The upcoming decades in particle physics will offer an unprecedented amount of data, opening new avenues to deepen our understanding of the fundamental laws of nature. On one hand, the High-Luminosity Large Hadron Collider (HL-LHC) will significantly enhance our experimental reach at the energy frontier. [...]
