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 ... -
