An Effective $p_T$ Cutoff for the Isolalated Lepton Background from Bottom Decay --
, 1993 There is a strong correlation between the $p_T$ and isolation of the lepton coming from $B$ decay. Consequently the isolated lepton background from $B$ decay goes down rapidly with increasing lepton $p_T$; and there is a $p_T$ cutoff beyond which it ...

Flavor in SU(5)$SU(5)$ Finite Grand Unified Models
Fortschritte der Physik, Volume 72, Issue 12, December 2024.Abstract Four SU(5)N=1$SU(5) \nobreakspace N=1$ supersymmetric models which exhibit S3$S_3$ and/or ZN$Z_N$ symmetries are studied, that are finite to two or all loops, and their corresponding mass matrices. The first is an all‐loop finite model based on an S3×Z3×Z2$S_3\times Z_3\times Z_2$ flavor symmetry, which leads to phenomenologically nonviable ...

Perturbations of bounce inflation scenario from f(T) modified gravity revisited
European Physical Journal C: Particles and Fields, 2019 In this work, we revisit the perturbations that are generated in the bounce inflation scenario constructed within the framework of f(T) theory. It has been well known that pure f(T) theory cannot give rise to bounce inflation behavior, so aside from the ...

The effect of real and virtual photons in the di-lepton channel at the LHC
, 2017 We present a study of di-lepton production at the CERN Large Hadron Collider with a particular focus on the contribution resulting from both real and virtual photons in the initial state.

Generation of Quantum Vortex Electrons with Intense Laser Pulses
Advanced Science, Volume 11, Issue 41, November 6, 2024.Wave functions of high‐energy electrons can be manipulated with ultra‐short intense laser pulses. Nonlinear scattering theory illustrates the efficient transfer of numerous spin angular momenta of laser photons to orbital angular momenta of scattered electrons, twisting electron wave functions into quantum vortex states.

Relating lepton mixing angles with lepton mass hierarchy [PDF]
International Journal of Modern Physics A, 2016 We revisit the possibility of relating lepton mixing angles with lepton mass hierarchies in a model-independent way. Guided by the existence of such relations in the quark sector, we first consider all the mixing angles, both in charged lepton and neutrino sectors to be related to the respective mass ratios.

Sustainable Development, Volume 32, Issue 5, Page 5538-5549, October 2024.Abstract Sustainable development serves as a guiding principle for societies aiming to progress beyond purely economic measures of well‐being. This paper constructs a composite indicator based on the framework of equitable and sustainable Well‐being (BES), integrating 105 indicators for Italian regions over the period 2018–2022.

Probing new physics signals with symmetry-restored Yukawa textures
European Physical Journal C: Particles and Fields, 2020 We implement a symmetry violation guideline into a two-Higgs-doublet model embedded with three right-handed neutrinos, and exploit the generic Yukawa structures of the model via a hypothetical symmetry restoration of a global $$U_Q(1)^3\times U_L(1)^3 ...

Secondary neutron dosimetry for conformal FLASH proton therapy
Medical Physics, Volume 51, Issue 7, Page 5081-5093, July 2024.Abstract Background Cyclotron‐based proton therapy systems utilize the highest proton energies to achieve an ultra‐high dose rate (UHDR) for FLASH radiotherapy. The deep‐penetrating range associated with this high energy can be modulated by inserting a uniform plate of proton‐stopping material, known as a range shifter, in the beam path at the nozzle ...

ChemPhysChem, Volume 25, Issue 12, June 17, 2024.Muonium, a light isotope of hydrogen, was added to the sulfur atom in thioformamide Mes*NHCH=S (Mes*=2,4,6‐tBu3C6H2) affording the C‐centered radical. The amino(mercapto)methyl radical in solution had the conventional structure containing slightly pyramidalized nitrogen and carbon.
