We present an observation of B -> eta'K*. The data sample corresponds to 232 x 10(6) BB pairs collected with the BABAR detector at the PEP-II asymmetric-energy B factory at the Stanford Linear Accelerator Center. We measure the branching fractions (in units of 10(-6)) B(B-0 -> eta'K-*0) = 3.8 +/- 1.1 +/- 0.5 and B(B+ -> eta'K*+) = 4.9(-1.7)(+1.9) +/- 0.8, where the first error is statistical and the second systematic.

Abstract
We present an observation of B -> eta'K*. The data sample corresponds to 232 x 10(6) BB pairs collected with the BABAR detector at the PEP-II asymmetric-energy B factory at the Stanford Linear Accelerator Center. We measure the branching fractions (in units of 10(-6)) B(B-0 -> eta'K-*0) = 3.8 +/- 1.1 +/- 0.5 and B(B+ -> eta'K*+) = 4.9(-1.7)(+1.9) +/- 0.8, where the first error is statistical and the second systematic. A simultaneous fit results in the observation of B -> eta'K-* with B(B -> eta'K-*) = 4.1(-0.9)(+1.0) +/- 0.5. We also search for B -> eta'rho and eta'f(0)(980)(f(0) -> pi(+) pi(-)) with results and 90% confidence level upper limits B(B+ -> eta'rho(+)) = 8.7(-2.8-1.3)(+3.1+2.3) (< 14), B(B0 -> eta'rho(0)) < 3.7, and B(B-0 -> eta'f(0)(980)(f(0) -> pi(+) pi(-))) < 1.5. Charge asymmetries in the channels with significant yields are consistent with zero.

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.
