Approaches to inclusive semileptonic B (s)-meson decays from Lattice QCD

Journal of High Energy Physics, 2023
We address the nonperturbative calculation of the inclusive decay rate of semileptonic B (s)-meson decays from lattice QCD. Precise Standard-Model predictions are key ingredients in searches for new physics, and this type of computation may eventually ...

Supergalactic Structure of Multiplets with the Telescope Array Surface Detector [PDF]

EPJ Web of Conferences, 2019
Evidence of supergalactic structure of multiplets has been found for ultra-high energy cosmic rays (UHECR) with energies above 1019 eV using 7 years of data from the Telescope Array (TA) surface detector.

Producing and detecting long-lived particles at different experiments at the LHC

Journal of High Energy Physics, 2022
We propose a new strategy to look for long-lived particles (LLP) at the LHC. The LLPs are produced at one experiment, but its decay products are detected by a detector at another experiment.

Effective gravitational couplings of four-dimensional N $$ \mathcal{N} $$ = 2 supersymmetric gauge theories

Journal of High Energy Physics, 2020
The low energy effective couplings of a four-dimensional N $$ \mathcal{N} $$ = 2 supersymmetric gauge theory to topological invariants of the background gravitational field are described by two functions A and B.

TA Anisotropy Summary [PDF]

EPJ Web of Conferences, 2019
The Telescope Array (TA) is the largest ultra-high-energy cosmic-ray (UHECR) detector in the northern hemisphere. It consists of an array of 507 surface detectors (SD) covering a total 700 km2 and three fluorescence detector stations overlooking the SD ...

High-Energy Neutrino Astronomy - Baikal-GVD Neutrino Telescope in Lake Baikal

Symmetry, 2021
High-energy neutrino astronomy is a fascinating new field of research, rapidly developing over recent years. It opens a new observation window on the most violent processes in the universe, fitting very well to the concept of multi-messenger astronomy ...

Distributed training and scalability for the particle clustering method UCluster [PDF]

EPJ Web of Conferences, 2021
In recent years, machine-learning methods have become increasingly important for the experiments at the Large Hadron Collider (LHC). They are utilised in everything from trigger systems to reconstruction and data analysis. The recent UCluster method is a

Predicting community college astronomy performance through logistic regression [PDF]

Physical Review Physics Education Research.19(2023), 2023
The present study examined demographic and academic predictors of astronomy performance of community college students enrolled in astronomy courses in a large suburban community college. The theoretical framework was based upon a deconstructive approach for predicting community college performance whereby students academic pathways through higher ...

High-Energy Neutrino Astronomy and the Baikal-GVD Neutrino Telescope [PDF]

Physics of Atomic Nuclei, 2020
Neutrino astronomy offers a novel view of the non-thermal Universe and is complementary to other astronomical disciplines. The field has seen rapid progress in recent years, including the first detection of astrophysical neutrinos in the TeV–PeV energy ...

Dark freeze-out cogenesis

Journal of High Energy Physics, 2022
We propose a new mechanism where a multi-component dark sector generates the observed dark matter abundance and baryon asymmetry and thus addresses the coincidence between the two.
