For the first time, differential inclusive-jet cross sections have been measured in neutral current deep inelastic ep scattering using the anti-k(T) and SIScone algorithms. The measurements were made for boson virtualities Q(2) > 125 GeV2 with the ZEUS detector at HERA using an integrated luminosity of 82 pb(-1) and the jets were identified in the Breit frame. The performance and suitability of the jet algorithms for their use in hadron-like reactions were investigated by comparing the measurements to those performed with the k(T) algorithm. Next-to-leading-order QCD calculations give a good description of the measurements. Measurements of the ratios of cross sections using different jet algorithms are also presented; the measured ratios are well described by calculations including up to O(alpha(3)(s)) terms. Values of alpha(s)(M-z) were extracted from the data; the results are compatible with and have similar precision to the value extracted from the kT analysis. (C) 2010 Elsevier B.V.

Abstract
For the first time, differential inclusive-jet cross sections have been measured in neutral current deep inelastic ep scattering using the anti-k(T) and SIScone algorithms. The measurements were made for boson virtualities Q(2) > 125 GeV(2) with the ZEUS detector at HERA using an integrated luminosity of 82 pb(-1) and the jets were identified in the Breit frame. The performance and suitability of the jet algorithms for their use in hadron-like reactions were investigated by comparing the measurements to those performed with the k(T) algorithm. Next-to-leading-order QCD calculations give a good description of the measurements. Measurements of the ratios of cross sections using different jet algorithms are also presented; the measured ratios are well described by calculations including up to O(alpha(3)(s)) terms. Values of alpha(s)(M(z)) were extracted from the data; the results are compatible with and have similar precision to the value extracted from the kT analysis. (C) 2010 Elsevier B.V.

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.
