Abstract Two related searches for phenomena beyond the standard model (BSM) are performed using events with hadronic jets and significant transverse momentum imbalance. The results based on a sample of proton–proton collisions at center-of-mass energy $$13\,\text {Te}\text {V} $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mn>13</mml:mn><mml:mspace/><mml:mrow><mml:mtext>Te</mml:mtext><mml:mspace/></mml:mrow></mml:mrow></mml:math> , collected by CMS experiment LHC...
A search for invisible decays of the Higgs boson produced via vector fusion (VBF) has been performed with 101 fb$^{-1}$ proton-proton collisions delivered by LHC at $\sqrt{s} =$ 13 TeV and collected CMS detector in 2017 2018. The sensitivity to VBF production mechanism is enhanced constructing two analysis categories, one based on missing transverse momentum, a second properties jets. In addition control regions Z W candidate events, highly populated region, photon association jets, used...
A bstract search for heavy neutral leptons (HNLs), the right-handed Dirac or Majorana neutrinos, is performed in final states with three charged (electrons muons) using proton-proton collision data collected by CMS experiment at $$ \sqrt{s} <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msqrt> <mml:mi>s</mml:mi> </mml:msqrt> </mml:math> = 13 TeV CERN LHC.

These could be due Flavor Changing Neutral Currents (FCNC) top sector induced...
Measurements of inclusive isolated-photon and photon+jet production in proton-proton collisions at s=13TeV are presented. The analysis uses data collected by the CMS experiment 2015, corresponding to an integrated luminosity 2.26 fb-1 . cross section for isolated photon is measured as a function transverse energy fiducial region. same region with identical requirements highest momentum jet.

Methods are presented for calibrating the hadron calorimeter system of CMS detector at LHC. The calorimeters experiment sampling brass and scintillator, in form one central two endcaps. These cover pseudorapidities |η| < 3 positioned inside solenoidal magnet.
