In the DsTau experiment at the CERN SPS (NA65), an independent and direct way to measure tau neutrino production following high energy proton interactions was proposed. As the main source of tau neutrinos is a decay of D-s mesons, produced in proton-nucleus interactions, the project aims at measuring a differential cross section of this reaction. The experimental method is based on a use of high resolution emulsion detectors for effective registration of events with short lived particle decays. Here we present the motivation of the study, details of the experimental technique, and the first results of the analysis of the data collected during test runs, which prove feasibility of the full scale study of the process in future.

Measurement of the differential cross-sections of inclusive, prompt and non-prompt J/psi production in proton-proton collisions at root s=7 TeV Aad, G.; et. al. (Elsevier BV, 2011-09-21) The inclusive production cross-section and fraction of mesons produced in B-hadron decays are measured in proton–proton collisions at with the ATLAS detector at the LHC, as a function of the transverse momentum and rapidity of the , using 2.3 pb−1 of integrated luminosity. The cross-section is measured from a minimum of 1 GeV to a maximum of 70 GeV and for rapidities within giving the widest reach of any measurement of production to date. The differential production cross-sections of prompt and non-pr...
Inclusive b-jet production in pp collisions at root s=7 TeV Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2012-04-01) The inclusive b-jet production cross section in pp collisions at a center-of-mass energy of 7TeV is measured using data collected by the CMS experiment at the LHC. The cross section is presented as a function of the jet transverse momentum in the range 18 < p(T) < 200 GeV for several rapidity intervals. The results are also given as the ratio of the b-jet production cross section to the inclusive jet production cross section. The measurement is performed with two different analyses, which differ in their tr...
Measurement of charm production in antineutrino charged-current interactions Onengut, G; et. al. (Elsevier BV, 2004-12-01) During the years 1994-1997, the emulsion target of the CHORUS detector was exposed to the wide-band neutrino beam of the CERN SPS collecting about 10(6) neutrino interactions. A measurement of (nu) over bar (mu)-induced charm production is performed by using the presence of a 5% (nu) over bar (mu) component in the nu(mu) beam. The measurement takes advantage of the capability to observe the decay topology in the emulsion. The analysis is based on a sample of charged-current interactions with at least one id...
Measurement of B(B)over-bar angular correlations based on secondary vertex reconstruction at root s=7 TeV Khachatryan, V.; et. al. (Springer Science and Business Media LLC, 2011-03-01) A measurement of the angular correlations between beauty and anti-beauty hadrons (B (B) over bar) produced in pp collisions at a centre-of-mass energy of 7 TeV at the CERN LHC is presented, probing for the first time the region of small angular separation. The B hadrons are identified by the presence of displaced secondary vertices from their decays. The B hadron angular separation is reconstructed from the decay vertices and the primary-interaction vertex. The differential B (B) over bar production cross s...
Cross section measurement of t-channel single top quark production in pp collisions at root s=13 TeV Sirunyan, A. M.; et. al. (Elsevier BV, 2017-09-01) The cross section for the production of single top quarks in the t channel is measured in proton- proton collisions at 13TeV with the CMS detector at the LHC. The analyzed data correspond to an integrated luminosity of 2.2fb(-1). The event selection requires one muon and two jets where one of the jets is identified as originating from a bottom quark. Several kinematic variables are then combined into a multivariate discriminator to distinguish signal from background events. A fit to the distribution of the ...
