An amplitude analysis of the final state structure in the B¯ s 0→ J/ψ K+ K-decay mode is
performed using 1.0 fb-1 of data collected by the LHCb experiment in 7 TeV center-of-mass …

In this paper, we propose three different strategies to extract the weak mixing angle ϕ s of
the B s system using penguin-mediated decays into vectors, mainly B s→ K* 0 K¯* 0, B s→ …

We analyze the non-leptonic decays B/B_s → ψ (2S) VB/B s→ ψ (2 S) V with V=(ρ, ω, K^*,
ϕ) V=(ρ, ω, K∗, ϕ) by employing the perturbative QCD (pQCD) factorization approach. Here …

The decay B¯ s 0→ J/ψ K+ K-is investigated using 0.16 fb-1 of data collected with the LHCb
detector using 7 TeV pp collisions. Although the J/ψ ϕ channel is well known, final states at …

In this work, we present an analysis of the nonleptonic charmonium modes B s 0→ J/ψ f
2′(1525) and B s 0→ J/ψ K+ K-. Within the framework of the factorization approach and …

In this paper, we present the branching ratio and polarization fraction of two body decay of B
s 0 to the vector mesons ϕ (1020) and X (3872) in which the X (3872) meson can be …

We discuss some topics concerning exclusive non-leptonic B decays. In particular we focus
on Bs-> KK decays, for which we present complementary predictions within the SM, as well …

The proton is one of the main building blocks of nature and therefore understanding its
spatial structure is essential. While its charge radius has been extensively studied, little is …

We propose some methods for studying hadronic sequential two-body decays involving
more spinning particles. It relies on the analysis of T-odd and T-even asymmetries, which …

In questo lavoro di tesie stato studiato lo spettro di massa invariante del sistema J/ψπ+ π-, m
(J/ψπ+ π-), in collisioni protone-protone a LHC, con energia nel centro di massa (√ s) pari a …
