Extended DBI and its generalizations from graded soft theorems

Journal of High Energy Physics, 2021
We analyze a theory known as extended DBI, which interpolates between DBI and the U(N) × U(N)/U(N) non-linear sigma model and represents a nontrivial example of theories with mixed power counting. We discuss symmetries of the action and their geometrical

Dosimetry with a phoswich detector [PDF]

EPJ Web of Conferences
A phoswich detector concept based on the combination of a high-Z element and a plastic element with a free running analogue-to-digital converter is presented in this work for the simultaneous measurement of operational dosimetric quantities H∗(10) and H′(

Analytic representation of all planar two-loop five-point Master Integrals with one off-shell leg

Journal of High Energy Physics, 2021
We present analytic expressions in terms of polylogarithmic functions for all three families of planar two-loop five-point Master Integrals with one off-shell leg. The calculation is based on the Simplified Differential Equations approach.

On the three-point order parameters of chiral symmetry breaking

Journal of High Energy Physics, 2023
The nonlocal order parameters of the QCD chiral symmetry breaking, namely the nonanomalous three-point Green functions of the quark bilinears belonging to the odd intrinsic parity sector, are studied within the framework of the Resonance chiral theory ...

GRBNeT – A prototype for an autonomous underwater neutrino detector

EPJ Web of Conferences, 2016
GRBNeT is a project aiming at the detection of ultra–high energy neutrinos, for example neutrinos originating from Gamma Ray Bursts. The goal is to design, construct and deploy a prototype unit of an autonomous (data/energy–wise) neutrino detector. Being

OPE of Green functions of chiral currents

Journal of High Energy Physics, 2020
In this paper, we investigate the high-energy behavior of two-point and three-point Green functions of the QCD chiral currents and densities using the framework of the operator product expansion in the chiral limit.

Feasibility of the experimental study of $$D_{s}^{*}\rightarrow {\phi }{\pi }$$ D s ∗ → ϕ π decay

European Physical Journal C: Particles and Fields, 2022
The current knowledge on the $$D_{s}^{*}$$ D s ∗ meson are very limited. Besides the dominant electromagnetic decays, the $$D_{s}^{*}$$ D s ∗ weak decays are legal and offer the valuable opportunities to explore the wanted $$D_{s}^{*}$$ D s ∗ meson.

Purely leptonic decays of the ground charged vector mesons

European Physical Journal C: Particles and Fields, 2021
The study of the purely leptonic decays of the ground charged vector mesons is very interesting and significant in determining the CKM matrix elements, obtaining the decay constant of vector mesons, examining the lepton flavor universality, and searching

Contributions from $${\Phi }_{B2}$$ ΦB2 to the B $${\rightarrow }$$ → PP decays within the QCD factorization

European Physical Journal C: Particles and Fields, 2019
With the potential for the improvements of measurement precision, the refinement of theoretical calculation on hadronic B weak decays is necessary. In this paper, we study the contributions of B mesonic distribution amplitude $${\Phi }_{B2}$$ ΦB2 within ...
