These detectors are sensitive to the charge released in the gas by ionizing radiation with energy deposits as low as few tens of electronvolts and also provide the topology of the ionization trail when coupled to suitable Micro Pattern Gas Detectors.

The increased beam power will also create significant challenges such as corrosion and radiation damage that can cause harmful effects on the material and degrade their mechanical and thermal properties during irradiation [...] 2023 - 1:18:18.

I will discuss some recent developments in this field, both from a theoretical perspective and from a more phenomenological point of view. [...] 2023 - 1:19:06.

In this talk, we propose such constraints for four-dimensional N=1 supergravities based on consistency of certain axionic, or EFT, strings. [...] 2023 - 1:12:18.

The production of tttt decays is one of the most rare processes at the LHC and among the most complex and rich signatures to study due to the large jet and lepton multiplicity in its final state.

The goal of this talk is to explain why these features are universal. [...] 2023 - 1:13:26. TH String Theory Seminar External link: Event details In : Infinite Distance Limits and Factorization

The measurements have attracted significant attention as the difference between the experimental world-average values of $R(D^*)$ and $R(D)$ and their theoretical prediction is at the level of three standard deviations [...] 2023 - 0:55:32.

In contrast to conventional image sensors, event vision sensors do not use a common sampling rate (=frame rate) for all pixels, but each individual pixel autonomously defines the timing of its own sampling points in response to its visual input by reacting to changes of incident light in continuous time.
