Lorentz Symmetry and High-Energy Neutrino Astronomy [PDF]

Universe, 2021
The search of the violation of Lorentz symmetry, or Lorentz violation (LV), is an active research field. The effects of LV are expected to be very small, and special systems are often used to search it.

Updates on the Hotspot and the Perseus-Pisces supercluster Excess Observed by the Telescope Array Experiment [PDF]

EPJ Web of Conferences, 2023
The Telescope Array (TA) experiment, the largest observatory studying ultra-high energy cosmic rays in the northern hemisphere, has reported evidence for two medium-scale anisotropies.

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.

W-boson production in polarized proton-proton collisions at RHIC through next-to-next-to-leading order in perturbative QCD

Physics Letters B, 2021
We perform a study of W-boson production in polarized proton-proton collisions through next-to-next-to-leading order (NNLO) in perturbative QCD. This calculation is required to extend the extraction of polarized parton distribution functions to NNLO ...

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 ...
