Internal multiplicity distributions of jets from nonlinear evolution within the jet function framework

open access: yesJournal of High Energy Physics
Jets selected with high internal charged-particle multiplicity exhibit markedly different substructure patterns compared to inclusive jet samples.

New physics in the angular distribution of B c − $$ {B}_c^{-} $$ → J/ψ(→ μ + μ − )τ − (→ π − ν τ ) ν ¯ τ $$ {\overline{\nu}}_{\tau } $$ decay

open access: yesJournal of High Energy Physics, 2021
In B c − $$ {B}_c^{-} $$ → J/ψ(→ μ + μ − )τ − ν ¯ τ $$ {\overline{\nu}}_{\tau } $$ decay, the three-momentum p τ − $$ {\boldsymbol{p}}_{\tau^{-}} $$ cannot be determined accurately due to the decay products of τ − inevitably include an undetected ν τ ...

Precise Measurements of the Leptonic Branching Ratios of the Tau Lepton [PDF]

open access: yesPhysical Review Letters, 1985
Precise measurements are reported for the leptonic branching ratios of the T lepton from the reaction e+e+ T+Tobserved with the MAC detector operating at PEP. Results from samples in which one T decays into three charged particles and the other to e or /,L are B, = 0.180 f 0.009 f 0.006 and B, = 0.183f0.009f0.005.

B ¯ s , d 0 $$ {\overline{B}}_{s,d}^0 $$ → J/ψμ + μ − decays in QCD factorization

open access: yesJournal of High Energy Physics
Motivated by the first LHCb searches for the rare B ¯ s , d 0 $$ {\overline{B}}_{s,d}^0 $$ → J/ψμ + μ − decays, we perform a detailed study of these processes within the QCD factorization formalism.

High p correlated tests of lepton universality in lepton(s) + jet(s) processes; An EFT analysis [PDF]

open access: yes, 2020
We suggest a new class of tests for searching for lepton flavor non-universality (LFNU) using ratio observables and based on correlations among the underlying LFNU new physics (NP) effects in several (seemingly independent) di-lepton and single lepton ...

Lepton number and lepton flavour violation in left-right symmetric models

open access: yes, 1998
The sources of lepton flavour and lepton number violation in the left-right symmetric models are reviewed and the most sensitive processes to these violations are discussed. Both the non-SUSY and SUSY versions of the theories are considered.

HERWIG 6: an event generator for Hadron emission reactions with interfering gluons (including supersymmetric processes) [PDF]

open access: yes, 2000
HERWIG is a general-purpose Monte Carlo event generator, which includes the simulation of hard lepton-lepton, lepton-hadron and hadron-hadron scattering and soft hadron-hadron collisions in one package. It uses the parton-shower approach for initial- and

Decoding cross-cultural textbook networks: structural patterns, formation mechanisms, and predictive insights using a topology–cognition framework

open access: yesEPJ Data Science
Conventional textbook analysis often faces fragmented frameworks, obscuring the relationship between content structure and cognitive development. To address this gap, we propose an integrative computational modeling framework that combines complex ...
