Results are presented from a search for the rare decays B-s(0) -> mu(+) mu(-) and B-0 -> mu(+) mu(-) in pp collisions at root s = 7 and 8 TeV, with data samples corresponding to integrated luminosities of 5 and 20 fb(-1), respectively, collected by the CMS experiment at the LHC. An unbinned maximum-likelihood fit to the dimuon invariant mass distribution gives a branching fraction 'B(B-s(0) -> mu(+)mu(-)) = (3.0(-0.9)(+1.0)) x 10(-9), where the uncertainty includes both statistical and systematic contributions. An excess of B-s(0) -> mu(+)mu(-) events with respect to background is observed with a significance of 4.3 standard deviations. For the decay B-0 -> mu(+)mu(-) an upper limit of 'B(B-0 -> mu(+) mu(-)) < 1.1 x 10(-9) at the 95% confidence level is determined. Both results are in agreement with the expectations from the standard model.
Results are presented from a search for the rare decays Bs0→μ+μ- and B0→μ+μ - in pp
collisions at √s=7 and 8 TeV, with data samples corresponding to integrated luminosities of
5 and 20 fb-1, respectively, collected by the CMS experiment at the LHC. An unbinned
maximum-likelihood fit to the dimuon invariant mass distribution gives a branching fraction
B(Bs0→μ+μ-)=(3.0-0.9+1.0) ×10-9, where the uncertainty includes both statistical and
systematic contributions. An excess of Bs0→μ+μ- events with respect to background is
observed with a significance of 4.3 standard deviations. For the decay B0→μ+μ- an upper
limit of B(B0→μ+μ-)<1.1×10 -9 at the 95% confidence level is determined. Both results
are in agreement with the expectations from the standard model.

Abstract
Results are presented from a search for the rare decays Bs0→μ+μ- and B0→μ+μ - in pp
collisions at √s=7 and 8 TeV, with data samples corresponding to integrated luminosities of
5 and 20 fb-1, respectively, collected by the CMS experiment at the LHC. An unbinned
maximum-likelihood fit to the dimuon invariant mass distribution gives a branching fraction
B(Bs0→μ+μ-)=(3.0-0.9+1.0) ×10-9, where the uncertainty includes both statistical and
systematic contributions. An excess of Bs0→μ+μ- events with respect to background is
observed with a significance of 4.3 standard deviations. For the decay B0→μ+μ- an upper
limit of B(B0→μ+μ-)<1.1×10 -9 at the 95% confidence level is determined. Both results
are in agreement with the expectations from the standard model.

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.
