Impact of background effects on the inclusive V cb determination
The determination of the CKM element V cb from inclusive semileptonic b → cℓ ν ¯ $$ \overline{\nu} $$ decays has reached a high precision thanks to a combination of theoretical and experimental efforts.

Hadroproduction of scalar P -wave quarkonia in the light-front k T -factorization approach
In this work, we present a thorough analysis of scalar P -wave χ Q0, Q = c, b quarkonia electromagnetic form factors for the γ ∗ γ ∗ → χ Q0 couplings, as well as their hadroproduction observables in k ⊥-factorisation using the light-front (LF) potential ...

Unparticle physics at hadron collider via dilepton production
The scale invariant unparticle physics recently proposed by Georgi could manifest at low energies as non integral number d_U of invisible particles. Unparticles if existing, could couple to the Standard Model fields and consequently affect the collider ...

Impact of isolation and fiducial cuts on q T and N-jettiness subtractions
Kinematic selection cuts and isolation requirements are a necessity in experimental measurements for identifying prompt leptons and photons that originate from the hard-interaction process of interest.

NNLO QCD corrections to leptonic observables in top-quark pair production and decay
We calculate a comprehensive set of spin correlations and differential distributions in top-quark pair production and decay to dilepton final states. Our calculation is performed in the Narrow Width Approximation.
