A search for a charged Higgs boson is performed with a data sample corresponding to an integrated luminosity of 19.7 ± 0.5 fb-1 collected with the CMS detector in proton-proton collisions at √{s}=8 ,TeV. The charged Higgs boson is searched for in top quark decays for m H± m t - m b, and in the direct production pp → t(b)H± for m H± > m t - m b

A search for a light pseudoscalar Higgs boson (A) produced in association with bottom quarks and decaying into a muon pair is reported. The search uses 19.7 fb-1 of proton-proton collisions at a center-of-mass energy of 8 TeV, collected by the CMS experiment. No signal is observed in the dimuon mass range from 25 to 60 GeV. Upper limits on the

A search for new physics in energetic, high-multiplicity final states has been performed using proton-proton collision data collected with the CMS detector at a center-of-mass energy of 13TeV and corresponding to an integrated luminosity of 2.3fb-1. The standard model background, dominated by multijet production, is determined exclusively from

Results are reported from a search for physics beyond the standard model in proton-proton collision events with a charged lepton (electron or muon), two jets identified as originating from a bottom quark decay, and significant imbalance in the transverse momentum. The search was performed using a data sample corresponding to 35.9 fb-1, collected by

A search for pair production of massive vector-like T and B quarks in proton-proton collisions at √{s}=13 TeV is presented. The data set was collected in 2015 by the CMS experiment at the LHC and corresponds to an integrated luminosity of up to 2.6 fb-1. The T and B quarks are assumed to decay through three possible channels into a heavy boson

We present deep images on the Hα emission plus an adjacent continuum obtained with OSIRIS/GTC, using the TF red in scanning mode for the Seyfert 2 galaxy Mrk 938. We detect HII regions so far (35 kpc) and two filaments with diffuse emission in the Hα pure images. We obtain Hα fluxes and we estimate velocities for these regions.
