About Double Parton Scattering at Short Relative Transverse Distances
Daniele Treleani, Giorgio Calucci
By working out the kinematics of double parton scattering at short relative transverse distances, we obtain an explicit link between the transverse centres of mass, of the two hard…
Multiple Parton Interactions, inclusive and exclusive cross sections, sum rules
D. Treleani, G. Calucci
In a simplified model of Multiple Parton Interactions the inclusive cross sections, of processes with large momentum transfer exchange, acquire the statistical meaning of factorial…
A Brief Comment on Multi-Gluon Amplitudes and Double Parton Interactions
Daniele Treleani, Giorgio Calucci
A typical contribution to a color ordered multi-gluon amplitude, which can split into two weakly correlated two-body gluon scattering amplitudes and may thus contribute to a Double…
A Theory-independent Way of Unambiguous Detection of Wino-like particles at LHC
G. Calucci, R. Iengo
We propose to use the change of the energy lost by ionization, measured by silicon detectors, before and after the passage through a bulk of dense matter, for unambiguously detecti…
A Brief Comment on Multi-Gluon Amplitudes and Double Parton Interactions
Daniele Treleani, Giorgio Calucci
A simplest case, where a contribution to a color ordered multi-gluon amplitude, describing a three body partonic interaction, can split into two weakly correlated two-body gluon sc…
Double Parton Scatterings in High-Energy Proton-Nucleus Collisions and Partonic Correlations
Giorgio Calucci, Simona Salvini, Daniele Treleani
The joint study of Double Parton Scatterings, in high energy proton-proton and proton-nucleus collisions, can provide a lot of information on multi-parton correlations. The multi-p…
Lower bound for the ratio of charged wino tracks to charged lepton tracks at LHC
Giorgio Calucci, Roberto Iengo
By using kinematical arguments we derive a theorem for the ratio: [production cross-section of charged-neutral wino pairs plus anything else] over [production cross-section of char…
Collisions of protons with light nuclei shed new light on nucleon structure
Daniele Treleani, Giorgio Calucci
The high rates of multi-parton interactions at the LHC can provide a unique opportunity to study the multi-parton structure of the hadron. To this purpose high energy collisions of…
Multi-Parton Interactions at the LHC
P. Bartalini, E. L. Berger, B. Blok +20
We review the recent progress in the theoretical description and experimental observation of multiple parton interactions. Subjects covered include experimental measurements of min…
Disentangling correlations in Multiple Parton Interactions
Giorgio Calucci, Daniele Treleani
Multiple Parton Interactions are the tool to obtain information on the correlations between partons in the hadron structure. Partons may be correlated in all degrees of freedom and…
Parton fluxes and virtual pions in heavy nuclei
Giorgio Calucci
The partonic flux originated from a heavy nucleus is not the mere sum of the fluxes coming from the individual nucleons. There are various effects that give rise to modifications.…
Multi-parton correlations and "exclusive" cross sections
G. Calucci, D. Treleani
In addition to the inclusive cross sections discussed within the QCD-parton model, in the regime of multiple parton interactions, different and more exclusive cross sections become…
Inclusive and "exclusive" cross sections in the regime of multiple parton collisions
Giorgio Calucci, Daniele Treleani
The large luminosity and the increased kinematical domain accessible at the LHC will allow to isolate large numbers of events with multiple parton collisions. Interestingly, the ha…
Screening in the QCD plasma: effects of the gluons and of the confinement
Giorgio Calucci, Enrico Cattaruzza
The effects of a thermalized gas of gluons in a q,q bar plasma is investigated. Then the interplay between Debye screening and confinement is analyzed in a simplified model. While…
Production of light particles by very strong and slowly varying magnetic fields
Giorgio Calucci, Antonino Di Piazza
The possibility that around some astrophysical objects there are non-static magnetic fields of enormous intensity suggests that in these situations real particles may be produced.…
Very strong and slowly varying magnetic fields as source of axions
Giorgio Calucci
The investigation on the production of particles in slowly varying but extremely intense magnetic field in extended to the case of axions. The motivation is, as for some previously…
Role of the gluons in the color screening in a QCD plasma
G. Calucci, E. Cattaruzza
The color screening in a QCD plasma, that was studied in a formulation making evident similarities and differences with the electric case, is continued by taking into account the c…
Pair production in a strong magnetic field: the effect of a strong background gravitational field
Antonino Di Piazza, Giorgio Calucci
We present the calculation of the probability production of an electron-positron pair in the presence of a strong magnetic field with time-varying strength. The calculation takes i…
