    Study of the p–p–K + and p–p–K - dynamics using the femtoscopy technique

    The interactions of kaons (K) and antikaons (K ̄) with few nucleons (N) were studied so far using kaonic atom data and measurements of kaon production and interaction yields in nuclei. Some details of the three-body KNN and K ̄ NN dynamics are still not well understood, mainly due to the overlap with multi-nucleon interactions in nuclei. An alternative method to probe the dynamics of three-body systems with kaons is to study the final state interaction within triplet of particles emitted in pp collisions at the Large Hadron Collider, which are free from effects due to the presence of bound nucleons. This Letter reports the first femtoscopic study of p–p–K + and p–p–K - correlations measured in high-multiplicity pp collisions at s = 13 TeV by the ALICE Collaboration. The analysis shows that the measured p–p–K + and p–p–K - correlation functions can be interpreted in terms of pairwise interactions in the triplets, indicating that the dynamics of such systems is dominated by the two-body interactions without significant contributions from three-body effects or bound states

    The process γγ→pp¯K+K- and its intermediate processes are measured for the first time using a 980 fb-1 data sample collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. The production of pp¯K+K- and a Λ(1520)0 (Λ¯(1520)0) signal in the pK- (p¯K+) invariant mass spectrum are clearly observed. However, no evidence for an exotic baryon near 1540 MeV/c2, denoted as Θ(1540)0 (Θ¯(1540)0) or Θ(1540)++ (Θ(1540)--), is seen in the pK- (p¯K+) or pK+ (p¯K-) invariant mass spectra. Cross sections for γγ→pp¯K+K-, Λ(1520)0p¯K++c.c. and the products σ(γγ→Θ(1540)0p¯K++c.c.)B(Θ(1540)0→pK-) and σ(γγ→Θ(1540)++p¯K-+c.c.)B(Θ(1540)++→pK+) are measured. We also determine upper limits on the products of the χc0 and χc2 two-photon decay widths and their branching fractions to pp¯K+K- at the 90% credibility level

    Abstract Using e + e − annihilation data sets corresponding to an integrated luminosity of 4.5 fb −1, collected with the BESIII detector at center-of-mass energies between 4.600 and 4.699 GeV, we report the first measurements of the absolute branching fractions B Λ c + → p K L 0 B(Λc+pKL0) \mathcal{B}\left({\Lambda}_c^{+}\to p{K}_L^0\right) = (1.67 ± 0.06 ± 0.04)%, B Λ c + → p K L 0 π + π − B(Λc+pKL0π+π) \mathcal{B}\left({\Lambda}_c^{+}\to p{K}_L^0{\pi}^{+}{\pi}^{-}\right) = (1.69 ± 0.10 ± 0.05)%, and B Λ c + → p K L 0 π 0 B(Λc+pKL0π0) \mathcal{B}\left({\Lambda}_c^{+}\to p{K}_L^0{\pi}^0\right) = (2.02 ± 0.13 ± 0.05)%, where the first uncertainties are statistical and the second systematic. Combining with the known branching fractions of Λ c + → p K S 0 Λc+pKS0 {\Lambda}_c^{+}\to p{K}_S^0 , Λ c + → p K S 0 π + π − Λc+pKS0π+π {\Lambda}_c^{+}\to p{K}_S^0{\pi}^{+}{\pi}^{-} , and Λ c + → p K S 0 π 0 Λc+pKS0π0 {\Lambda}_c^{+}\to p{K}_S^0{\pi}^0 , we present the first measurements of the K S 0 KS0 {K}_S^0 - K L 0 KL0 {K}_L^0 asymmetries R Λ c + K S , L 0 X = B Λ c + → K S 0 X − B Λ c + → K L 0 X B Λ c + → K S 0 X + B Λ c + → K L 0 X R(Λc+,KS,L0X)=B(Λc+KS0X)B(Λc+KL0X)B(Λc+KS0X)+B(Λc+KL0X) R\left({\Lambda}_c^{+},{K}_{S,L}^0X\right)=\frac{\mathcal{B}\left({\Lambda}_c^{+}\to {K}_S^0X\right)-\mathcal{B}\left({\Lambda}_c^{+}\to {K}_L^0X\right)}{\mathcal{B}\left({\Lambda}_c^{+}\to {K}_S^0X\right)+\mathcal{B}\left({\Lambda}_c^{+}\to {K}_L^0X\right)} in charmed baryon decays: R Λ c + p K S , L 0 = − 0.025 ± 0.031 R(Λc+,pKS,L0)=0.025±0.031 R\left({\Lambda}_c^{+},p{K}_{S,L}^0\right)=-0.025\pm 0.031 , R Λ c + p K S , L 0 π + π − = − 0.027 ± 0.048 R(Λc+,pKS,L0π+π)=0.027±0.048 R\left({\Lambda}_c^{+},p{K}_{S,L}^0{\pi}^{+}{\pi}^{-}\right)=-0.027\pm 0.048 and R Λ c + p K S , L 0 π 0 = − 0.015 ± 0.046 R(Λc+,pKS,L0π0)=0.015±0.046 R\left({\Lambda}_c^{+},p{K}_{S,L}^0{\pi}^0\right)=-0.015\pm 0.046 . No significant asymmetries with statistical significance are observed
