Study of the nonleptonic charmless $$B \rightarrow SS$$ B → S S decays with the QCD factorization approach

European Physical Journal C: Particles and Fields, 2023
Inspired by the brilliant prospects of the ongoing B meson experiments, the hadronic charmless B $${\rightarrow }$$ → SS decays are studied by considering the next-to-leading (NLO) contributions with the QCD factorization approach, where S denotes the ...

Physics of particle detection [PDF]

AIP Conference Proceedings, 1998
In this review the basic interaction mechanisms of charged and neutral particles are presented. The ionization energy loss of charged particles is fundamental to most particle detectors and is therefore described in more detail. The production of electromagnetic radiation in various spectral ranges leads to the detection of charged particles in ...

Solar neutrino probes of the muon anomalous magnetic moment in the gauged U 1 L μ − L τ $$ \mathrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$

Journal of High Energy Physics, 2020
Models of gauged U 1 L μ − L τ $$ \mathrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$ can provide a solution to the long-standing discrepancy between the theoretical prediction for the muon anomalous magnetic moment and its measured value.

A New Cosmological Paradigm: the Cosmological Constant and Dark Matter [PDF]

, 1998
The Standard Cosmological Model of the 1980's is no more. I describe the definitive evidence that the density of matter is insufficient to result in a flat universe, as well as the mounting evidence that the cosmological constant is not zero.

Particle physics models of inflation [PDF]

, 2007
Inflation models are compared with observation on the assumption that the curvature perturbation is generated from the vacuum fluctuation of the inflaton field. The focus is on single-field models with canonical kinetic terms, classified as small- medium-

Parity doubling in particle physics [PDF]

, 2007
Parity doubling in excited hadrons is reviewed. Parity degeneracy in hadrons was first experimentally observed 40 years ago. Recently new experimental data on light mesons caused much excitement and renewed interest to the phenomenon, which still remains

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
