Measurements of the branching fractions of Λ c +  → pπ − π +, Λ c +  → pK−K+, and Λ c +  → pπ −K+

open access: yesJournal of High Energy Physics, 2018
The ratios of the branching fractions of the decays Λ c +  → pπ − π +, Λ c +  → pK − K +, and Λ c +  → pπ − K + with respect to the Cabibbo-favoured Λ c +  → pK − π + decay are measured using proton-proton collision data collected with the LHCb ...

λ-similar bases [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1987
Corresponding to an arbitrary sequence space λ, a sequence {xn} in a locally convex space (l.c.s.) (X,T) is said to be λ-similar to a sequence {yn} in another l.c.s.

On λ D − R0 And λ D − R1 Spaces [PDF]

open access: yes, 2020
In this paper we introduce the new types of separation axioms called λ D − R0 and λ D − R1 spaces, by using λ D-open set. The notion λ D − R0 and λ D − R1 spaces are introduced and some of their properties are investigated.namiq, sarhad-will be generated-

Search for Λ ¯ - Λ Baryon-Number-Violating Oscillations in the Decay J/ψ →pK- Λ ¯ + c. c [PDF]

open access: yes, 2023
We report on the first search for Λ¯-Λ oscillations in the decay J/ψ→pK-Λ¯+c.c. by analyzing 1.31×109 J/ψ events accumulated with the BESIII detector at the BEPCII collider. The J/ψ events are produced using e+e- collisions at a center of mass energy s=3.

Measurement of the forward-backward asymmetry of Λ and Λ¯ production in pp¯ collisions [PDF]

open access: yes, 2016
We study Λ and Λ¯ production asymmetries in pp¯→Λ(Λ¯)X, pp¯→J/ψΛ(Λ¯)X, and pp¯→μ±Λ(Λ¯)X events recorded by the D0 detector at the Fermilab Tevatron collider at s√=1.96  TeV.

Search for Λ −¯Λ oscillation in / →Λ⁢¯Λ decay [PDF]

open access: yes
Using (10087 ±44) ×106  / decays collected by the BESIII detector at the BEPCII collider, we search for baryon number violation via Λ −¯Λ oscillation in the decay / →Λ⁢¯Λ. No evidence for Λ −¯Λ oscillation is observed.

Study of the kinematic dependences of Λ b 0 production in pp collisions and a measurement of the Λ b 0 → Λ c + π − branching fraction [PDF]

open access: yes, 2014
The kinematic dependences of the relative production rates, fΛ0b/fd, of Λ b 0 baryons and B 0 mesons are measured using Λ b 0 → Λ c + π − and B¯¯0 →D+π− decays.

Hadronic structure functions in the e+e−→Λ¯Λ reaction

open access: yesPhysics Letters B, 2017
Cross-section distributions are calculated for the reaction e+e−→J/ψ→Λ¯(→p¯π+)Λ(→pπ−), and related annihilation reactions mediated by vector mesons.

Is different Λ and Λ¯ polarization caused by different spatio-temporal freeze-out picture?

open access: yesPhysics Letters B, 2020
Thermal vorticity in non-central Au+Au collisions at energies 7.7≤s≤62.4 GeV is calculated within the UrQMD transport model. Tracing the Λ and Λ¯ hyperons back to their last interaction point we were able to obtain the temperature and the chemical ...
