Key4hep-TURNKEY SOFTWARE FOR FUTURE COLLIDERS

期刊: ACTA PHYSICA POLONICA B, 2021; 52 (8)

Future collider experiments rely on a well-maintained software for their physics performance studies and detector optimisation. The Key4hep project ai......

SOLITARY WAVE TRANSITION FROM LOW TO HIGH ENERGY IN THE FERMI-PASTA-ULAM LATTICE

期刊: ACTA PHYSICA POLONICA B, 2021; 52 (9)

In this paper, we study analytically and numerically the solitary wave transition from low to high energy in localization, the relation between energy......

ENTROPY AND TEMPERATURE OF THE THREE-LEVEL SYSTEM: THE MICRO-CANONICAL ENSEMBLE METHOD

期刊: ACTA PHYSICA POLONICA B, 2021; 52 (5)

Based on the micro-canonical ensemble (MCE) theory and the method of steepest descend, we rederive a formula for the entropy and the temperature in th......

A NOVEL INTEGRATED APPROACH FOR ANALYZING THE FINANCIAL TIME SERIES AND ITS APPLICATION ON THE STOCK PRICE ANALYSIS

期刊: ACTA PHYSICA POLONICA B, 2021; 52 (9)

With the advent of the big data era, the ever-increasing accumulated financial data plays a significant role in people's daily life. The ensemble meth......

HIGGS CROSS-SECTION MEASUREMENTS IN THE FOUR-LEPTON FINAL STATE AT CMS

期刊: ACTA PHYSICA POLONICA B, 2020; 51 (6)

Cross sections of the Higgs (H) boson are measured in the H -> ZZ -> 4l (l = e, mu) decay channel. The full data sample of proton-proton collisi......

SEARCH FOR A NEW HEAVY RESONANCE IN FINAL STATES WITH DI-JET OR DI-b-JETS WITH THE ATLAS DETECTOR

期刊: ACTA PHYSICA POLONICA B, 2020; 51 (6)

A search of new heavy resonances decaying into a pair of jets in pp collisions with the ATLAS detector at LHC is reported. The dataset corresponds to ......

STUDYING THE EXOTIC DECAY Kr-70 -> Br-70

期刊: ACTA PHYSICA POLONICA B, 2020; 51 (3)

Beta-decay of the very neutron-deficient Kr isotope, Kr-70, was studied at RIKEN-RIBF using the EURICA cluster array. The experiment significantly inc......

RESOURCES ALLOCATION STRATEGIES OF DISEASE CONTROL IN MULTIPLEX NETWORKS

期刊: ACTA PHYSICA POLONICA B, 2020; 51 (8)

During the prevention and control of epidemics, both disease-related awareness diffusion and disease treatment require resources investment, so it is ......

COMBINED FIT TO THE CROSS SECTIONS OF e(+)e(-) -> pi Z(c)(3900) -> pi pi J/psi AND e(+)e(-) pi Z(c)(3900) -> pi D(D)over-bar

期刊: ACTA PHYSICA POLONICA B, 2020; 51 (10)

The cross sections of e(+)e(-) -> pi Z(c)(3900) -> pi pi J/psi and e(+)e(-) pi Zc(3900) ->pi D (D) over bar have been measured by the BESIII ......

SYNCHRONIZATION OF COMPLEX NETWORK BASED ON THE THEORY OF GRAVITATIONAL FIELD

期刊: ACTA PHYSICA POLONICA B, 2019; 50 (1)

Based on the conception of gravitational field, the issue of synchronization of complex network turns to the interaction and motion of particles under......
