Diffractive photoproduction of D*(+/-)(2010) mesons was measured with the ZEUS detector at the ep collider HERA, using an integrated luminosity of 78.6 pb(-1). The D* mesons were reconstructed in the kinematic range: transverse momentum p(T)(D*) > 1.9 GeV and pseudorapidity |eta( D*)| < 1.6, using the decay D*(+) -> D(0)pi(+)(s) followed by D(0) -> K(-) pi(+)(+c.c.). Diffractive events were identi. ed by a large gap in pseudorapidity between the produced hadronic state and the outgoing proton. Cross sections are reported for photon-proton centre-of-mass energies in the range 130 < W < 300 GeV and for photon virtualities Q(2) < 1 GeV(2), in two ranges of the Pomeron fractional momentum x(IP) < 0.035 and x(IP) < 0.01. The relative contribution of di. ractive events to the inclusive D*(+/-) (2010) photoproduction cross section is about 6%. The data are in agreement with perturbative QCD calculations based on various parameterisations of di. ractive parton distribution functions. The results are consistent with di. ractive QCD factorisation.

Abstract
Diffractive photoproduction of D*(+/-)(2010) mesons was measured with the ZEUS detector at the ep collider HERA, using an integrated luminosity of 78.6 pb(-1). The D* mesons were reconstructed in the kinematic range: transverse momentum p(T)(D*) > 1.9 GeV and pseudorapidity |eta( D*)| < 1.6, using the decay D*(+) -> D(0)pi(+)(s) followed by D(0) -> K(-) pi(+)(+c.c.). Diffractive events were identi. ed by a large gap in pseudorapidity between the produced hadronic state and the outgoing proton. Cross sections are reported for photon-proton centre-of-mass energies in the range 130 < W < 300 GeV and for photon virtualities Q(2) < 1 GeV(2), in two ranges of the Pomeron fractional momentum x(IP) < 0.035 and x(IP) < 0.01. The relative contribution of di. ractive events to the inclusive D*(+/-) (2010) photoproduction cross section is about 6%. The data are in agreement with perturbative QCD calculations based on various parameterisations of di. ractive parton distribution functions. The results are consistent with di. ractive QCD factorisation.

simulazione ASN
Il report seguente simula gli indicatori relativi alla propria produzione scientifica in relazione alle soglie ASN 2023-2025 del proprio SC/SSD. Si ricorda che il superamento dei valori soglia (almeno 2 su 3) è requisito necessario ma non sufficiente al conseguimento dell'abilitazione. La simulazione si basa sui dati IRIS e sugli indicatori bibliometrici alla data indicata e non tiene conto di eventuali periodi di congedo obbligatorio, che in sede di domanda ASN danno diritto a incrementi percentuali dei valori. La simulazione può differire dall'esito di un’eventuale domanda ASN sia per errori di catalogazione e/o dati mancanti in IRIS, sia per la variabilità dei dati bibliometrici nel tempo. Si consideri che Anvur calcola i valori degli indicatori all'ultima data utile per la presentazione delle domande.
La presente simulazione è stata realizzata sulla base delle specifiche raccolte sul tavolo ER del Focus Group IRIS coordinato dall’Università di Modena e Reggio Emilia e delle regole riportate nel DM 589/2018 e allegata Tabella A. Cineca, l’Università di Modena e Reggio Emilia e il Focus Group IRIS non si assumono alcuna responsabilità in merito all’uso che il diretto interessato o terzi faranno della simulazione. Si specifica inoltre che la simulazione contiene calcoli effettuati con dati e algoritmi di pubblico dominio e deve quindi essere considerata come un mero ausilio al calcolo svolgibile manualmente o con strumenti equivalenti.
