Toward high performance solution retrieval in multiobjective clustering
(Elsevier, 2019-10)
The massive generation of unlabeled data of current industrial applications has attracted the interest of data mining practitioners. Thus, retrieving novel and useful information from these volumes of ...
Study of B0s → J/ψπ+π−K+K− decays
(Springer, 2021-02)
The decays B0s → J/ψπ+π−K+K− are studied using a data set corresponding to an integrated luminosity of 9 fb−1, collected with the LHCb detector in proton-proton collisions at centre-of-mass energies of ...
Classifying Microcalcifications in Digital Mammograms using Machine Learning techniques
(4rt Congrés Català d'Intel.ligència Artificial, Barcelona, 24-25 d'octubre de 2001, 2001-10)
This paper presents a Computer Aided Diagnosis (CAD) of breast cancer from mammograms. The first part involves severa! image processing techniques, which extract a set of features from the microcalcifications ...
Search for the Rare Decays B0s→e+e− and B0→e+e−
(American Physical Society, 2020-05)
A search for the decays B0s→e+e− and B0→e+e− is performed using data collected with the LHCb experiment in proton-proton collisions at center-of-mass energies of 7, 8, and 13 TeV, corresponding to ...
Observation of Multiplicity Dependent Prompt χc1(3872) and ψ(2S) Production in pp Collisions
(2021-03)
The production of χc1(3872) and ψ(2S) hadrons is studied as a function of charged particle multiplicity in pp collisions at a center-of-mass energy of 8 TeV, corresponding to an integrated luminosity ...
Search for long-lived particles decaying to e ± μ∓ ν
(Springer, 2021-03)
Long-lived particles decaying to e±μ∓ν, with masses between 7 and 50GeV/c2 and lifetimes between 2 and 50ps, are searched for by looking at displaced vertices containing electrons and muons of opposite ...
