Study of the process e+e- →π+π-π0 using initial state radiation with BABAR
(Journal article; Peer reviewed, 2021)The process e+e−→π+π−π0γ is studied at a center-of-mass energy near the Υ(4S) resonance using a data sample of 469 fb−1 collected with the BABAR detector at the PEP-II collider. We have performed a precise measurement of ... -
Study of the rare decays of B_s^0 and B^0 mesons into muon pairs using data collected during 2015 and 2016 with the ATLAS detector
(Peer reviewed; Journal article, 2019-04-15)A study of the decays B 0s → μ+μ− and B0 → μ+μ− has been performed using 26.3 fb−1 of 13 TeV LHC proton-proton collision data collected with the ATLAS detector in 2015 and 2016. Since the detector resolution in μ+μ− invariant ... -
Study of the reactions e + e − → 2ðπ + π − Þπ0π0π0 and 2ðπ + π − Þπ0π0η at center-of-mass energies from threshold to 4.5 GeV using initial-state radiation
(Journal article; Peer reviewed, 2021)We study the processes e+e−→2(π+π−)π0π0π0γ and 2(π+π−)π0π0ηγ in which an energetic photon is radiated from the initial state. The data were collected with the BABAR detector at SLAC. About 14 000 and 4700 events, respectively, ... -
Study of the reactions e + e − → π + π − π0π0π0π0 and π + π − π0π0π0η at center-of-mass energies from threshold to 4.5 GeV using initial-state radiation
(Journal article; Peer reviewed, 2021)We study the processes e+e−→π+π−π0π0π0π0γ and π+π−π0π0π0ηγ in which an energetic photon is radiated from the initial state. The data were collected with the BABAR detector at the SLAC National Accelerator Laboratory. About ... -
Study of the seismic source parameters and its relation with other seismic engineering parameters
(Doctoral thesis, 2013-04-17)The term seismic source refers to the sources which can generate seismic waves. The seismic source of tectonic earthquakes is represented as a displacement discontinuity on a plane surface as a result of shear faulting. ... -

Study of the Λ–Λ interaction with femtoscopy correlations in pp and p–Pb collisions at the LHC
(Peer reviewed; Journal article, 2019-10-10)This work presents new constraints on the existence and the binding energy of a possible Λ–Λ bound state, the H-dibaryon, derived from Λ–Λ femtoscopic measurements by the ALICE collaboration. The results are obtained from ... -
A study of transfer rates of phenols from caustic to crude oil
(Peer reviewed; Journal article, 2019-04)Phenol and phenolic compounds are a common problem in various industries, due to their ability to dissolve in aqueous solutions, such as caustic. Caustic is used in several industrial operations for pH adjustments and for ... -
Study of very forward energy and its correlation with particle production at midrapidity in pp and p-Pb collisions at the LHC
(Journal article; Peer reviewed, 2022)The energy deposited at very forward rapidities (very forward energy) is a powerful tool for characterising proton fragmentation in pp and p-Pb collisions. The correlation of very forward energy with particle production ... -
A study of Λ and ¯Λ polarization splitting by meson field in PICR hydrodynamic model
(Journal article; Peer reviewed, 2021)With the PICR hydrodynamic model, we study the polarization splitting between Λ and Λ¯ at RHIC BES energy range, based on the meson field mechanism. Our results fit to the experimental data fairly well. Besides, two ... -
A Study on Continuous Max-Flow and Min-Cut Approaches
(Chapter; Peer reviewed, 2010)We propose and investigate novel max-flow models in the spatially continuous setting, with or without supervised constraints, under a comparative study of graph based max-flow / min-cut. We show that the continuous max-flow ... -
A study on iterative methods for Richards' equation
(Peer reviewed; Journal article, 2016-04)This work concerns linearization methods for efficiently solving the Richards equation, a degenerate elliptic-parabolic equation which models flow in saturated/unsaturated porous media. The discretization of Richards’ ... -
A study on local weather variability in complex terrain using the Bergen School Mesonet
(Master thesis, 2017-08-15)This thesis investigates local- to mesoscale variability in winds, temperature and precipitation and is based on data delivered by a network of school weather stations in the greater surrounding of Bergen, Norway. The high ... -
A study on the Atmospheric Boundary Layer in the High Arctic during winter
