DESCRIPTION:Speakers: Soumya Sadhukhan (Ramakrishna Mission Residential Co
 llege\, Kolkata\, India and Vivekananda Centre for Research)\nExtensions o
 f the Standard Model with charged Higgs\, having a non-negligible coupling
  with neutrinos\, can have interesting implications vis-à-vis neutrino ex
 periments. Such models can leave their footprints in the ultra-high energy
  neutrino detectors like IceCube in the form of neutrino non-standard inte
 ractions (NSIs) which can also be probed in lower energy neutrino experime
 nts. We consider a model based on the neutrinophilic two-Higgs doublets an
 d study its imprints in the recently reported excess neutrino events in th
 e PeV energy bins at the IceCube. An additional signature of the model is 
 that it also leads to sizeable NSIs. We perform a combined study of the la
 test IceCube data along with various other constraints arising from neutri
 no experiments e.g.\, Borexino\, TEXONO\, COHERENT\, DUNE\, and T2HK\, tog
 ether with the limits set by the LEP experiment\, and explore the paramete
 r space which can lead to a sizeable NSI.\n\nhttps://indico.ific.uv.es/eve
