P is for Phenomenology

But Is It Phenomenology?

Phenomenology of single spin asymmetries in p ↑ p → πX

A general formalism, based on factorization theorem and pQCD hard interactions, is developed for the description of single spin effects in hadron-hadron inclusive processes. The transverse momentum, k⊥, of the quarks inside the hadrons and of the hadrons relatively to the fragmenting quark, is taken into account in distribution and fragmentation functions, and leads to possible non zero single ...

P-value: What is and what is not

The misinterpretation and misuse of p-value have been increasing for decades. In March 2016, the American Statistical Association released a statement to warn about the use and interpretation of p-value. In this study, we provided a definition and discussion of p-value and emphasized the importance of its accurate interpretation.    

Impact-Picture Phenomenology for π±p, K±p and pp, p̄p Elastic Scattering at High Energies

We present an extension to πp and Kp elastic scattering at high energies of the impactpicture phenomenology we first proposed more than twenty years ago, for pp and p̄p elastic scattering. We show, in particular, that the analytic form of the opacity function for the proton obtained previously is compatible with the experimental results on πp and Kp elastic scattering at high energies. It is pro...

When every $P$-flat ideal is flat

In this paper‎, ‎we study the class of rings in which every $P$-flat‎ ‎ideal is flat and which will be called $PFF$-rings‎. ‎In particular‎, ‎Von Neumann regular rings‎, ‎hereditary rings‎, ‎semi-hereditary ring‎, ‎PID and arithmetical rings are examples of $PFF$-rings‎. ‎In the context domain‎, ‎this notion coincide with‎ ‎Pr"{u}fer domain‎. ‎We provide necessary and sufficient conditions for‎...
