The flavour changing neutral current decay b→sγ has been detected in hadronic Z decays collected by ALEPH at LEP. signal is isolated lifetime-tagged bb̄ events the presence of a hard photon associated with system high momentum and rapidity hadrons. background processes are normalised from data themselves. inclusive branching ratio measured to be(3.11±0.80stat±0.72syst)×10−4,consistent Standard Model expectation via penguin processes.
Previously published and as yet unpublished QCD results obtained with the ALEPH detector at LEP1 are presented. The unprecedented statistics allows detailed studies of both perturbative non-perturbative aspects strong interactions to be carried out using hadronic Z tau decays. presented include precise determinations coupling constant, tests its flavour independence, SU(3) gauge structure QCD, study coherence effects, measurements single-particle inclusive distributions two-particle...
LHCf is an experiment dedicated to the measurement of neutral particles emitted in very forward region LHC collisions. The physics goal provide data for calibrating hadron interaction models that are used study Extremely High-Energy Cosmic-Rays. This possible since laboratory equivalent collision energy 1017 eV. Two detectors, consisting imaging calorimeters made tungsten plates, plastic scintillator and position sensitive sensors, installed at zero degree angle ±140 m from point (IP)....
The differential cross sections for inclusive neutral pions as a function of transverse and longitudinal momentum in the very forward rapidity region have been measured at Large Hadron Collider (LHC) with detector (LHCf) proton-proton collisions $\sqrt{s}=$ 2.76 7 TeV proton-lead nucleon-nucleon center-of-mass energies $\sqrt{s_\text{NN}}=$ 5.02 TeV. Such are compatible hypotheses limiting fragmentation Feynman scaling. Comparing collisions, we find sizable suppression production after...
In early 2010, the Large Hadron Collider forward (LHCf) experiment measured very neutral particle spectra in LHC proton–proton collisions. From a limited data set taken under best beam conditions (low beam-gas background and low occurrence of pile-up events), single photon at s=7 TeV pseudo-rapidity (η) ranges from 8.81 to 8.99 10.94 infinity were obtained for first time are reported this Letter. The two independent LHCf detectors consistent with one another serve as cross check data. also...
The Large Hadron Collider forward (LHCf) experiment is designed to use the LHC verify hadronic-interaction models used in cosmic-ray physics. Forward baryon production one of crucial points understand development showers. We report neutron-energy spectra for s=7 TeV proton–proton collisions with pseudo-rapidity η ranging from 8.81 8.99, 8.99 9.22, and 10.76 infinity. measured energy obtained two independent calorimeters Arm1 Arm2 show same characteristic feature before unfolding detector...
The integration of remote sensing and deep learning has revolutionized environmental monitoring, leveraging cutting-edge technologies to assist the decision-making processes in resource management offering advanced tools for rapid disaster response.

The final results of the ALEPH search for Standart Model Higgs boson at LEP, with data collected in year 2000 center-of-mass energies up to 209 GeV, are presented. changes respect preceding publication described and a complete study systematic effects is reported. findings this analysis confirm preliminary published November shortly after closing down LEP collider: significant excess events observed, consistent production 115 GeV/c2 Standard boson. searches neutral bosons od MSSM also...
This chapter of the "Flavor in era LHC" workshop report discusses flavor-related issues production and decays heavy states at LHC high momentum transfer Q, both from experimental theoretical perspective. We review top quark physics, discuss flavor aspects several extensions standard model, such as supersymmetry, little Higgs models or with extra dimensions. includes discovery aspects, well measurement properties these states. also present publicly available computational tools related to this topic.
A search for the production and non-standard decay of a Higgs boson, h, into four taus through intermediate pseudoscalars, a, is conducted on 683 pb−1 data collected by ALEPH experiment at centre-of-mass energies from 183 to 209 GeV. No excess events above background observed, exclusion limits are placed combined cross section times branching ratio, $ {\xi^2} = \frac{{\sigma \left( {{\text{e}^{+} }{\text{e}^{-} } \to {\text{Zh}}} \right)}}{{{\sigma_{\text{SM}}}\left( \right)}} \times B\left(...
The inclusive production rate of neutral pions in the rapidity range greater than y=8.9 has been measured by Large Hadron Collider forward (LHCf) experiment during s=7 TeV proton-proton collision operation early 2010. This paper presents transverse momentum spectra pions. from two independent LHCf detectors are consistent with each other and serve as a cross-check data. also compared predictions several hadronic interaction models that often used for high-energy particle physics modeling...
E896 has measured Lambda production in 11.6A GeV/c Au-Au collisions over virtually the whole rapidity phase space. The midrapidity p(t) distributions have been for first time at this energy and appear to indicate that hyperons different freeze-out conditions than protons. A comparison with relativistic quantum molecular dynamics model shows while there is good shape agreement high predicts significantly slopes of m(t) spectra midrapidity. data, where overlap occurs, are consistent previously...
