 Search for Excited Quark Resonances in the Photon $+$ Jet Invariant Mass Spectrum at 13 TeV / Sharma, Varun (Delhi U.) /CMS We present a search for excited quarks ( $q^{*}$ ) decaying into a photon and a hadronic jet in proton-proton collisions at $\sqrt{s} = 13\,$ TeV with the CMS experimentCMS experiment. High transverse momentum photons and jets are selected to search for a resonance peak in the continuous invariant mass distribution of the photon $+$ jet system.

 Resonance Measurements in p–Pb Collisions at $\sqrt{s_\mathrm{{NN}}}$ = 5.02 TeV with ALICE / Sahoo, Sarita (Bhubaneswar, Inst. Phys.) /ALICE Hadronic resonances serve as unique probes in the study of hot and dense nuclear matter produced in heavy-ion collisions. Measurements of resonance production in pp and p–Pb collisions provide the reference for studies in heavy-ion collisions. [...] 2018 - 3 p. - Published in : Springer Proc.

 Excited States Searches for Light and Heavy Flavour Quarks with CMS Data at $\sqrt{s} = 13$  TeV / Garg, Rocky Bala (Delhi U.) ; Sharma, Varun (Delhi U.) ; Choudhary, Brajesh C (Delhi U.) In this paper, a search for excited states of light u,d and heavy b quark has been presented using the data collected by CMS detector at $\sqrt{s} = 13$  TeV in proton-proton collisons at the LHC. The resonance for these states have been probed in $\gamma$ +Jet final state and 95 $\%$ confidence level upper limits on the product of cross sectionCross section and branching fraction are evaluated as a function of the excited quark mass in the absence of any signal.. 2018 - 3 p. - Published in : Springer Proc.

 Search for the Pair-Production of First Generation Leptoquarks in pp Collisions at $\sqrt{s}$ = 13 TeV / Bhat, M A (Tata Inst.) ; Mahakud, B (Tata Inst.) ; Cooper, S I (Alabama U.) ; Mohanty, G B (Tata Inst.) ; Aziz, T (Tata Inst.) ; Rumerio, P (Alabama U.) The quark and lepton sectors of the standard model (SM) are strikingly similar in terms of the number of particles and generations. This hints at a fundamental symmetry existing between the two sectors. [...] 2018 - 4 p. - Published in : Springer Proc.

 Long Range Correlations in P–Pb Collisions at $\sqrt{s_\mathrm{{NN}}}$ = 5.02 TeV with ALICE / Koyithatta Meethaleveedu, Greeshma (Indian Inst. Tech., Mumbai) /ALICE Collaboration Angular correlation measurements between charged particles revealed the existence of a double-ridge in p–Pb collisions. Similar correlations between particles separated by several units of pseudorapidity in Pb–Pb collisions were attributed to collectivity in heavy ion collisions.
